Simply said, a gravel bike is a combination of a road bike (happy on smooth pavement) and a mountain bike (happy playing rough and tumble in the mud). Mellow single tracks, farm roads, gravel, crushed cobblestones, rough city streets, tarmac — whatever. A gravel bike is a machine that’s capable of performing on various surfaces, while sustaining comfort. Gravel bikes like the Discover have 650b wheels with wider tires that run at a lower pressure, a slightly more upright posture, and thicker forks that can handle rougher roads. These small changes give a road bike like performance with more comfortable riding on un-paved roads. Gravel bikes like the Discover also have braze-ons (holes for screws) for connecting front and rear racks, and are a popular choice for road cyclist on long rides, bike messengers, urban commuting with bags or kids, bike camping, and long distance touring. It is important to note that a gravel bike is NOT a mountain bike and does not have shocks and cannot take jumps, or big drops. It is still a road bike and intended for on-road use. The definition of what it means to be “on-road” is just much broader then your typical road bike, giving you the freedom to explore some wild and beautiful places.
Why are Hilltopper Bikes 1/2 the price of other e-bikes on the market? Because we sell direct to you, the customer. Our mission is to create a sustainable future, two wheels at a time and we do that by making e-bikes affordable for you. We intentionally don’t sell through dealers, distributors, or retailers because that way of selling means a higher price tag for you. We build our kits and bike wheels with love and care here in Seattle and sell direct to you, so you won’t see the large retail markup that would be present if you were buying from a third party. That way you’re always getting the best deal on your electric bike.
It depends on how fast you want to go, and how steep the hill. The 36v, 350 watt kits and bikes can go 20 mph with minimal pedaling. This is the legal limit in most of the US for e-bikes so it’s enough power for most bikes. This is a great power for steeper hills, faster commutes carrying bigger loads. It’s like having two Soul Cycle instructors also pedaling for you. The 36v, 250 watt Sprinter kit can go 16 mph with minimal pedaling on flat ground, but they perform best as a boost to your pedaling with pedaling required on hills. Perfect if you are looking for an added boost to your ride at an affordable price. Cuts your commute time by 25%, flattens out that hill by 50% puts a smile on your face. The 48v, 750 watt Summit kit can go 20 mph with minimal pedaling. This is the legal limit in most of the US for e-bikes. The motor could go faster, but it is limited at 20 mph for safety and to remain street legal in the US (unlimited it could go 30 mph). The 750 watt motor can carry large loads up steep hills and accelerates quickly. Perfect if you are looking to cruise consistently at 20 mph over varied terrain or climb absurdly steep and long hills while hauling groceries. It’s more power then you might need. But its a lot of fun and gives you the piece of mind that you can accelerate out of any sticky situation.
All Hilltopper electric bikes and kits have a maximum speed of 20 mph. This keeps them street legal and compliant with state laws and city ordinances in the US. For choosing a power system, here’s what to keep in mind: The 36v, 350 watt kits (Horizon) can go 20 mph with minimal pedaling. This is great for steeper hills, faster commutes carrying bigger loads. The 36v, 250 watt kits (Sprinter) can go 15 mph with minimal pedaling on flat ground, but they perform best as a boost to your pedaling with pedaling required on hills. Perfect if you are looking for an added boost to your ride at an affordable price. Cuts your commute time by 25%, gives a boost up hills puts a smile on your face.

SOFTRIDE VOM ANDEREN STERN
Unkonventionell und innovativ. das spezielle Design unseres Rahmens ist von der Tierwelt inspiriert und setzt kompromisslos neue Maßstäbe. Das Hinterrad wird unter Ausnutzung der Materialeigenschaften in einem organischen Verbund elastisch aufgehängt. Getauft auf den Namen Softride, gleicht dieses innovative Fahrwerk, in sich geschlossen und ohne zusätzliche Federsysteme, Fahrbahnunebenheiten aus.
Gekontert wird der so gewonnene Fahrkomfort durch eine brachiale Tretlager- und Lenkkopfsteifigkeit, die formgebend über den 3D-Druck realisiert werden konnten. Eingebrachte Leistung wird ohne Umwege in direkten Vortrieb verwandelt, während sich das Cockpit leicht und äußerst präzise steuern lässt. Fahrkomfort trifft auf Agilität. Puristisch in der Erscheinung punktet der Softride-Rahmen auf den zweiten Blick mit funktionaler Integrationstiefe, die das Herz eines jeden Technik-Nerds höherschlagen lässt. Geschaffen für die Überholspur!
GEBALLTE E-POWER VORAUS
Im stählernen Skelett des Softride-Rahmens tobt das elektrische X35 Kraftwerk von MAHLE ebikemotion. Unsichtbar im Unterrohr integriert, versorgt die leichte Akkueinheit mit 250 Wh den kompakten Heckmotor im Hinterrad, der mit satten 40 Nm Drehmoment für bis zu 100 km dynamisch unterstützt. Der am Lenker befindliche iWoc Trio gewährleistet volle Konnektivität und kommuniziert via Bluetooth und ANT in 3 Schaltstufen mit dem Motor und informiert jederzeit mit einer haptischen Vibration über die Aktivitäten.
Dank Smart Bike App und SP-Connect wird das Cockpit zum smarten Dashboard über das der Elektroantrieb zusätzlich angepasst, Fahrten navigiert und vielseitig getrackt werden können. Stichwort Tracking. ein smarter Diebstahlschutz kann optional im Softride-Rahmen versteckt werden, um diebischen Elstern jederzeit auf die Schliche zu kommen.
Und dann wäre da noch das LED-Lichtsystem. hierbei handelt es sich um die kleinste StVZO zugelassene Optik, die sich unauffällig in das Cockpit integriert und das Gefilde weitläufig ausleuchtet. Das LED-Rücklicht versteckt sich hingegen in der Sattelstütze und macht dank einer 5-Dot-LED-Matrix prominent auf sich aufmerksam.

INTEGRIERTES FRONTLICHT
Sehen und gesehen werden: Mit dem LED-Frontlicht aus dem Hause LightSKIN integrieren wir die kleinste StVZO zugelassene Optik in das Cockpit. Mit einer enormen Lichtausbeute wird die Nacht zum Tag und Hindernisse werden frühzeitig ins Visier genommen. Am hinteren Ende hält die 5-Dot-Led-Matrix in der Sattelstütze den Verkehr jederzeit zuverlässig und sichtbar auf Distanz. Etwas ausgestellt, wird das Warnlicht auch seitlich im teils unübersichtlichen Dschungel wahrgenommen. StVZO zugelassen und wie ein Leuchtturm beständig am Strahlen.
SOFTRIDE-STAHLRAHMEN
Der innovative Softride-Rahmen ist der erste seiner Art und rückt den Werkstoff in ein gänzlich neues Licht der Möglichkeiten. Das 3D-gedruckte Monocoque-Design ist facettenreich und definitiv ein Sprung in Richtung Zukunft. Der spezielle Hinterbau hängt das Hinterrad elastisch auf und garantiert spürbaren Fahrkomfort, ohne an Tretlagersteifigkeit einbüßen zu müssen. Im Gegenteil, der Vortrieb erfolgt explosiv und lässt ein jedes E-Bike nur so nach vorn schnellen. Apropos. der Softride-Rahmen ist ein echtes Leichtgewicht und Anpassungskünstler. Die modulare Plattformarchitektur lässt sich jederzeit unter puristischen Aspekten anpassen und erweitern. elektrische Raffinessen und Züge integrieren sich hierbei nahezu unsichtbar, denn das Auge isst bekanntlich mit.

INTEGRIERTE AKKUEINHEIT
Es kommt eben doch auf die inneren Werte an. Und so versenken wir die 250 Wattstunden von MAHLE ebikemotion mal eben unauffällig in Unterrohr. Versorgt wird die X35 Akkueinheit über eine Ladebuchse oberhalb des Tretlagers über ein 230V-Netzteil, nicht größer als das eines Notebooks. Aufgeladen in bis zu 4h, versorgt das Powerhaus den Heckmotor mit dem nötigen Saft und treibt ausdauernd für bis zu 100 Kilometer an. Und sollte einmal der Saft ausgehen, kann der Riegel zu Wartungszwecken über das Tretlager ausgetauscht werden.
KRAFTVOLLER HECKMOTOR
Immer unter Strom bringt das elektrische Kraftpaket ganze 40 Nm genau dort auf die Straße, wo es gebraucht wird. nämlich am Heck unseres Softride Rahmens. Mit der kompakten Größe fällt der MAHLE ebikemotion X35 Heckmotor kaum ins Auge. Auch das Gewicht ist hier gänzlich zu vernachlässigen, denn der Motor gehört zu den leichtesten seiner Klasse. Angesteuert wird er über den iWoc Trio Daumenschalthebel am Cockpit. Über 3 Schaltstufen. Eco, Urban, Sport. sprintet das Technikwunder nur so nach vorn und lässt sich dank HG Standard gar mit einem Zahnriemen- oder Kettenschaltungsantrieb mechanisch erweitern. Technik-Nerds kommen ebenfalls auf ihre Kosten und können den Motor via Smart Bike App zusätzlich konfigurieren. Ein äußerst smarter Zeitgenosse mit ordentlich Leistung im Gepäck.
KETTENANTRIEB
Mit der präzisen Shimano GRX Kettenschaltung fliegen Bäume und Berge nur so an dir vorbei! Entwickelt für die rauen Gravel-Abenteuer, spielt die Schaltgruppe ihre mechanische Übersetzungsvielfalten über 11 Gänge hinweg aus. Die spezifische Ergonomie und Robustheit macht das Gravel zu einem einzigartigen Genuss. Leise und stabil gleitet die robuste KMC Lightweight Kette über ein hochwertiges Garbaruk Narrow-Wide Kettenblatt aus europäischem Hause. Das perfekte Setup für wilde Touren durch das Unterholz!

So darf das nächste Abenteuer gern etwas ausufern.
OPTIONALE FEDERGABEL
Die Lauf Grif Federgabel ist definitiv nicht von diesem Planeten und bringt in Ergänzung zu unserem Softride-Rahmen ordentlich Komfort ins Cockpit.

PURISTISCHE GEPÄCKTRÄGER
Die optionalen Gepäckträger verwandeln das URWAHN E-Bike in einen Packesel. Für das kleine Abenteuer tritt der Lowrider auf die Bühne.

Der Tubus Evo Fly ist ein echter Purist und auf das Wesentliche reduziert. Doch der Schein trügt, denn der Top- und Sideloader stemmt bis zu 20 Kilogramm und rüstet für den nächsten Biwak. Auf ins urwahnsinnige Abenteuer!

Mit unserer speziellen Geometrie wagen wir den Goldenen Schnitt und führen die drei Segmente URBAN, GRAVEL und ROAD in einer ergonomisch sinnvollen Ausrichtung zusammen. Das Ergebnis ist eine komfortable Geometrie mit progressiven Eigenschaften in sportiver Sitzhaltung. Ein gewagter Ansatz, der pures Fahrvergnügen verspricht und alle Trends überdauert. Achtung, Suchtgefahr! Der kürzere Radstand verspricht absolute Wendigkeit, während die nach vorn ausgestellte Gabel Laufruhe bei höheren Geschwindigkeiten garantiert. Das Tretlager ist mittelhoch aufgehangen und interagiert über die kurzen Kettenstreben direkt mit dem Hinterrad. So wird jeglicher Krafteinsatz über die überdurchschnittliche Tretlagersteifigkeit umgehend in Vortrieb verwandelt. Das Steuerrohr ist mittelhoch ausgeführt und verspricht mit einem 1.5″ Lagerstandard eine hohe Lenkkopfsteifigkeit, die über präzise Einschläge an das Vorderrad übertragen wird. Das Oberrohr fällt dynamisch nach hinten ab und begünstigt die Überstandshöhe zugunsten jener Größenperzentile von Frau und Mann, wodurch ferner auch die Steifigkeit des Gesamtsystems dankbaren Einfluss erfährt. Summa Summarum haben wir die perfekte Symbiose aus allen Bereichen in einem sehr agilen Setting vereint.

GT Grade Current: How To Cheat Death On A Gravel eBike
The Silver Comet Trail is a 61.5 mile stretch of smoothly paved two-lane trail located in the heart of good ol’ Paulding County Georgia. It’s a favorite of runners and bikers alike, but If you’re a local to the area, it carries a much more sinister connotation: The Silver Comet is haunted. It’s a bonafide urban legend, tainted by reoccurring headlines of violent boogeymen, murders, and assaults. First was the murder back in 2006, then an assault in 2014, followed by another assault in 2019.
If you think I’m exaggerating, you need look no further than the local government’s website on “Trail Safety Tips” for the Silver Comet, which recommends the following to its residents:
“Bring self-protection: Though rare, there’s been crime on the trail. When asking 35 random people on the trail if they were armed, the majority carried protection.”
Most cyclists would shudder at the thought of adding 850 grams of loaded Glock 19 to their pack, and don’t even get me started on the aerodynamic implications… But on the Silver Comet… Well… The majority feel otherwise.
With that being said, the Silver Comet also happens to be the ideal place to put the new GT Grade Current gravel bike through its paces. With no shortage of offshoots leading down scenic country roads, long climbs, gravel descents, and a smattering of low-traffic public lands to explore, it’s almost perfect… Supernatural, even…
22 GT Grade Current: Price, Specs, Etc.
It was an unseasonably warm and beautiful day in mid-December when I arrived at the trailhead and unloaded GT’s latest Grade Current, which is the new pedal-assisted version of their immensely popular Grade gravel bike. The original Grade was (and still is) a thoroughly well-made and capable machine, and was actually good enough to take home Bike Radar’s 2020 gravel bike of the year award against stiff competition from brands like Cannondale and Trek.
You’d be forgiven for mistaking the Grade Current for its pedal-powered stablemate: GT managed to incorporate both the battery and motor assemblies into what is essentially the exact same size and shape frame of the original. They accomplished this wizardry by opting for a rear hub-driven Mahle X35 motor connected to a 250W battery hidden inside the downtube. It takes a trained eye to recognize the Current as an eBike, which is particularly enjoyable when passing hard-core cyclists you’d normally never have a chance at keeping up with (especially on steep climbs). That extra 40Nm of torque-on-demand is no joke.
The pedal-assist control system is tucked away clandestinely into the top tube, and is controlled either by a simple one-button interface (which also serves as your power level and battery life indicator via multi-colored backlighting) or via the Mahle/ebikemotion app, which also allows you to set custom motor maps, view the battery life, range, and charging status of your bike, and also functions as an impromptu cycling computer that records your rides, time, distance, battery discharge, etc.
There are three power modes to choose from – Green, orange, and red – With green providing the longest range and lowest level of assistance, red giving you full power at the cost of range, and orange striking a happy medium between the two. Once you’ve selected a power mode, the light on the downtube changes into a battery life indicator, cycling from white to green to orange and then finally to red as your battery approaches critical mass.
There are two models of the “eGrade” available in the US: The GT Grade Current that we tested, which is a commuter-biased version with a flat handlebar, 1×10 gears, and a sleek double black paint scheme, and the GT Grade Bolt, which is more enthusiast-focused with drop bars, 2×10 gears, and upgraded Shimano GRX cranks and derailleurs. Both bikes share the same aluminum frame, carbon fork, motor, battery, wheels, etc.
The Grade Current that we tested goes for an MSRP of 3,350, while the upmarket Grade Bolt will cost you 4,200.
Riding The GT Grade Current Electric Gravel Bike
Although I knew damn well that GT’s claimed range of roughly 40-45 miles was accurate, I decided to tackle a 51-mile loop known locally as Blue Car Body Rd. I figured it was the perfect test for an electric gravel bike, as dedicated gravel riders typically enjoy the kind of outright masochism that only a 100 mile ride can provide. I needed to know that the bike was still functional after the battery ran out of juice, so I bravely offered my body as sacrifice for the greater good of our readership.
A few notes here before we get into the nitty-gritty: I am not a long-distance cyclist. I am not in the kind of shape that 50 mile bike rides require. But hey… I had an eBike to do the work for me, right? What’s a short 5-10 mile stretch without the battery?
As far as the bike itself goes, I can honestly say that I’m a fan. GT has done a remarkable job of building a smooth pedaling machine that takes the sting out of painfully steep climbs and handles confidently on fast downhill sections, both on gravel and windy tarmac. It’s a hoot to ride.
I generally stick to the middle “orange” power setting, as it gives a helpful boost when you need it without feeling like outright cheating. If you really want decadence, throw it in the red setting, and pedal as much or as little as you want: The bike will charge forward. I watched my 70-year-old father climb the steepest hill on his street in red mode: He’s in far worse shape than myself, yet rather than cursing and wheezing, he was grinning uncontrollably and loving every minute of it.
I’ll also give serious props to GT for their floating seat-stay frame design: When we read about road bikes, gravel bikes, or pretty much any “rigid” two-wheeler, there’s a lot of marketing BS about “frame compliance” thanks to carbon fiber here, titanium there, geometry this and that… They’re rigid. They are about as compliant as your typical suspect on an episode of COPS.
The Grade is definitely rigid, but I was pleasantly surprised by the amount of “spring” GT had worked into the aluminum frame while working my way down bone-shaking rocky descents. The Grade doesn’t feel like a mountain bike, but riding it over rough terrain doesn’t hurt nearly as much as it should. Cudos.
The wide flat handlebar specced on our Grade Current gives tons of leverage and control for off-road situations, especially when moving at speed downhill. I was definitely craving the variety of hand/body positions that a drop bar provides after about 20 miles in the saddle, but even the widest drop bars feel nervous and twitchy on rough terrain, and I was happy to have it in the rougher sections.
Riding The GT Grade Current With A Dead Battery On A Haunted Trail…
Life is peachy on an electric bike as long as it’s got juice. Around the time I hit mile 40, the red ring of death started flashing up at me from the top tube, alerting me that I had entered the
Interestingly enough,I also noted at this time that (a) my iPhone battery (and therefore my GPS) was also dying and that (b) the sun was setting alarmingly fast. At this point, I had roughly 17 miles left to go (I missed a turn or two and had to do some backtracking), had no idea where I was, was in a dense section of forest, and hadn’t seen another human being for the better part of an hour.
How much further did I have until I was back on paved roads? How many more goddamn steep gravel hills were waiting for me in between? And then it dawned on me: Even if I made it back to pavement by nightfall, I’d be pedaling the last 6 miles back to the truck on… The Silver Comet Trail…
At this point I was exhausted, borderline delirious, and starting to feel what a great man once referred to as “The Fear.”
My legs had been screaming at me since mile 20, and around mile 30 my feet had started to do this lovely twitching thing every time I stood up on the pedals. For the 106th time that day, I told myself “Just get it done.” and got back to chipping away at the remaining miles.
Night fell fast, and as I descended the last offensively steep and rocky decline of the WMA, all the colors of the woods began blurring into the same monotone grey, and I could barely see the path ahead of me. It was also at this time I noted my GPS (now courageously holding onto 1% of battery) was telling me I had once again missed a turn, and after checking and rechecking the route incredulously, I realized my path back to the eerie silence of the Silver Comet Trail was… (You’ve gotta be kidding me)… A winding stretch of narrow singletrack (all uphill) that I was struggling to find the entrance of thanks to a thick layer of pine straw and the failing light of the day.
As I (somehow) managed to locate the narrow entrance to the trailhead, the red light on the Grade gave its last apologetic blink, and strangely, I felt… Alone. My 250W riding buddy had called it a day. Did anyone else know where I was?
Totally not panicking, I dropped the bike into its lowest of ten gears, and much to my relief, found that yes: It COULD move uphill under pedal power alone.
Don’t get me wrong… It was work. Hard work. The kind of thing a reasonably intelligent and out-of-shape person might assume pedaling a 35-pound bike uphill would feel like after 40-something miles of mixed surface riding. But by god… It was doing it.
I emerged onto The Silver Comet just 10 minutes later, and almost felt relief until I realized I could barely make out the dotted yellow line diving the two sides of the path. There wasn’t a single light in sight, although there must have been a mile of uninterrupted pathway ahead of me.
Dark trees loomed high above the trail, their branches stretching out over overhead to form a deep and ominous tunnel.
“Just get it done.” I said for the 107th time that day, and every two minutes after that.
I was in limp mode, sipping the last ounce of water from my Camelback while I squinted and strained to make out the trail in front of me.
Shapes emerged from the woods nearby as I pedaled, and I began to wonder how much of what I was seeing was real and how much was delirium. I pedaled on. Just get it done.
I rode another five miles under a starless sky with cramps creeping up my legs before I reached the final tunnel that sat between me and my truck another mile down the trail. Blinding lights filled the tunnel, destroying the night vision I’d been working so hard to preserve as I strained to FOCUS on the darkness at its exit… And that’s when I heard it…
“Hey man.” said a voice from the end of the tunnel.
Panic gripped me, as all my worst fears came to fruition. I kept waiting on the adrenaline to hit and fuel my now useless legs as I approached the end of the tunnel, but it never came.
“HEY.” the voice called out again into the tunnel, now louder, more assertive.
“Hey?” I answered as I breached the tunnel exit, completely blind to the woods around me.
“Hey man.” I heard as a shadowy figure stepped out onto the trail in front of me.
Electric Gravel Bikes: Lessons Learned
I didn’t wait to find out who the man at the end of the tunnel was, or why we was waiting there, of all places, in the pitch dark with high hopes and (presumably) an unlit cigarette.
I sped past, and didn’t look back until I was safely under the glow of the parking lot lights, where I promptly loaded GT’s fantastic new Grade Current into the bed of my truck, climbed pitifully into the cab, locked the doors, and made my way back toward civilization, a handful of ibuprofen, and a cold beer.
In the cruel light of day, I asked myself the following questions:
Do electric gravel bikes make sense? Who should buy one? What should you know before you do?
I think electric gravel bikes make complete sense. With that being said, I also think you should be aware and respectful of their range. You need to be in much better shape than myself to pedal one long distances after the battery calls it quits. Had my last 6 miles not been on a smooth paved surface, I suspect a search party would still be out looking for me today.
So who should buy one? Well, gravel bikes go by several names. They’re endurance bikes, they’re bikepacking rigs, they’re “adventure” bikes, all rolled into one. They’re also fantastic commuter bikes, especially when they’ve got electric motors backing them up. The GT Grade Current is the perfect tool for weekday commuters who want to try their hand at medium-distance touring and gravel riding. Your average commuter will get a full week’s worth of round trips to the office out of this bike on a single charge. Three hours on a wall charger takes the GT from 0% to 100%, so while you can’t exactly charge it mid-ride, you can certainly have it charged and ready to go for a weekend ride by the time you wake up Saturday morning.
And what should you know before getting your own? Well, for starters, you need to know your physical capability, and how that scales with the bike’s range. Don’t be like me and plan on finding out the hard way how capable you really are after it’s too late to turn back… Especially if your route takes you through the middle of nowhere on a haunted trail in rural Georgia.
Aside from that? Just know that it’s a blast to ride both on-road and off. These bikes have no business on mountain bike singletrack, but they’re surprisingly comfortable on rough terrain, and an absolute pleasure on well-groomed gravel roads. Buy one, enjoy it, let your old man enjoy it, and should you ever happen to take it on the Silver Comet Trail, consider bringing self-protection.
RLT e9 RDO
We’re calling it our first e-gravel bike, but it’s more like a pedal-powered SUV. Or an overland expedition vehicle. Or an urban ninja transit device. Our design details make this new bike equally at home across a range of environments, rolling over a broad swath of surfaces. Bosch powered, cargo capable, front suspension-ready, and flat-bar friendly, there’s almost no transportation task this chameleon can’t handle
The e-version of our vaunted RLT gravel bike goes far and it goes fast. The Bosch Performance Line Speed drive system propels a rider to 28 miles per hour (Performance Line CX and 25kph in the EU) with a 500wh battery for longer distances. Bosch leads the category with reliable motors that deliver smooth, lag-free pedal assist, backed by an unparalleled global service network.
What’s not so obvious are the details, starting with our RDO carbon construction. Our engineers wanted the battery to be integrated and yet easily externally removable for the utmost flexibility when recharging. However, this design presents engineering challenges that we solved in elegant fashion.
Using FEA modeling and extensive testing, lead engineer George Parry built a robust carbon backbone structure to withstand the roughest roads imaginable. In fact, the RLT e9 RDO passes ISO mountain bike test standards. Bonded to a 1-piece alloy motor mount, this machine is ready to go the distance for years to come.
Subtle design features add incredible versatility. Post-mount disc brake fitment makes it easy to change to a flat handlebar with mountain bike brakes. Likewise, our intentional inclusion of Boost hub and crankset spacing allows the rider interchangeability with mountain bike drivetrain parts. And the all-new RLT e9 RDO carbon fork is the same length as a FOX AX suspension fork. There’s even routing for a dropper seatpost.
For a dose of rugged utility, Niner’s custom, integrated racks are available to carry supplies for a trip to the office or a ride around the world. Clearance for comfortable 50c tires and fitment for fenders round out this chameleon-like gravel bike.
If you can dream it, the RLT e9 RDO can do it. Gravel roads around the globe beckon this bike, as do social trails through town, bike paths, and even urban alleyways. Adventure waits for you, but don’t keep it waiting
