Discover its lightness and folding

1.1. How do Flebis work?

Flebis are lightweight folding bicycles that incorporate pedal assisted system, which means you can pedaling and the electric motor acts assisting you to take you to a speed of between 20-25km/h. At the time you brake the motor stops working.

1.2. What do I need to drive a Flebi bike?

Unlike motorcycles and cars, electric bicycles do not need any permission nor do you need insurance to travel on public roads, as long as they have the EN15194 certificate which regulates electric bicycles in the European Union. Flebi has obtained through the recognized agency TUV:

1.3. Which Flebi model is more convenient for me?

All of them are electric, folding and light, but there are some details that make them cover different needs. Flebi Evo is probably the lightest e-bike in the market, so you can carry it comfortably, even at your back inside the backpack (optional). It can be easily folded and provides a máximum power of 250W which allows to climb any slope. Flebi Power is slightly heavier but it builts gear changes in return, so you can ride almost any terrain. Finally the Flebi Supra has the maximum power in the market too, more autonomy, you can comfortably remove the battery and fold it in a second. The frame is larger, more robust and stable, and it weighs 17.5kg.

1.4. Is Flebi adequate for my height and weight?

Flebi Evo and Supra supports a maximum weight of 110kg, and the recommended height for a comfortable driving position is between 1.50 and 1.85m. Flebi Power is limited to 100kg and max height of 1.80m.

1.5. Will I be able to go up the hills that are in my way?

Sure! The Flebi Evo features a powerful 250W motor and 24V battery that allows you to climb easily hills having a slope up to 15% while pedaling.

2.1. What autonomy does and how it charge the battery?

Flebi Evo incorporates a long-term Lithium battery integrated inside the frame that provides a range between 35 and 40km approx. To recharge it, just connect the included power adapter to the bike itself and in 2-3 hours the LED will turn green to show that the charge cycle is complete. The battery is not removable by design and safety reasons.

2.2. Can the battery be recharged with the energy of pedaling?

Although it would be very interesting, the battery can not be charged with the movement itself because the power it provides is not sufficiently strong or stable.

2.3. Can I charge it in the car or caravan?

Yes, you can find In the market power adapters that convert the DC voltage of the vehicles to AC voltage that requires de Flebi charger.

2.4. Can I use the Flebi Evo as a normal bike?

Yes, just switching the display off the electric assistance of Flebi is disconnected and then it works as a conventional folding bike.

2.5. What is the usage of the display of the Flebi Evo?

It has two functions. The first is being an indicator of remaining battery level, shown with 3 red lights that get off as the battery is going down. The second is to select the intensity of the pedaling assistance between 3 levels available. The higher will advance farther with each pedal stroke but will reduce the battery lenght as well.

2.6. When do I have to replace the battery, how much it costs and where I can do?

The Flebi Evo battery lasts around 600 recharge cycles, even though their lifetime strongly depends on the weight of the person and the level of tire pressure.

You can replace it at the store where you purchased your bike or directly contacting our Flebi Technical Service. If you purchase the bike online then you only have to buy the new battery and send the bike to us. We will replace it for free.

3.1. Will I receive the Flebi ready to use?

Virtually. You will get you Flebi carefully packed in folded position, ready to use. Just screw the pedals and make sure the wheels are inflated to the proper pressure. The battery comes with a slight charge from factory and it is recommended to make a first full cycle after draining it completely. When unfolded checks then chain is correctly placed on plate and sprocket by giving a pedaling backward

3.2. Do I need to recharge it before every ride?

No. The lithium-ion technology of the battery does not have a memory effect that prevents the full charge if it has not previously been completely discharged. Therefore the battery can be charged at any time, even it is recommended to wait until it gets completely out.

3.3. Can the electrical components get damaged if the bike gets wet?

Although the bicycle is waterproof and safe, it is not advisable a long drive in the rain to prevent water from entering inside the frame as it could affect the internal battery and electrical components.

3.4. Can I install a kids chair to the Flebi?

Flebi Evo is a bike intended for personal transportation. The rear carrier can support a weight of up to 15kg, but due to its size we do not recommend to couple a second seat for safety reasons.

4.1. Does it need any specific kind of maintenance for being electric?

Not particularly. As with any other bike, you should regularly check the most common parts (wheels, brake pads, cables), check the lubricant at the chain and clean the bike. Avoid high pressure cleaner since it may cause damage to electrical components. To preserve the life of the battery it is recommended to charge it completely and wait until it gets out.

4.2. What should I do if I will not use it for a while?

In occasional use conditions it is recommended to keep the Flebi protected against dust and humidity. You should it store it with a minimum level of battery, but not discharged, and do a full charge cycle every 2 months even when it is not used.

4.3. What is the warranty period and what I do if I have a problem?

The warranty is one year for electrical components and two years for rest of parts, except those of normal wear out. If you had to do any typical repairment you can do it in conventional bike shops. For electrical parts you should do it in the store where you purchased the bike, as they have the knowledge and right parts, or contacting our Customer Service if you bought directly at Flebi Store.

4.4. Can I purchase spare parts?

Sure. In Flebi we have a large stock of spare parts including every component of our bikes. If you need any of them just search at our online stores or contact us to request it in case you can’t find it there.

REVIEW: BULLS COPPERHEAD EVO AM EMTB – A GERMAN ELECTRIC EVOLUTION

Bulls is a German brand established in 1995 that gained credibility when its riders Karl Platt and Stefan Sahm won the Cape Epic multiple times on its Copperhead model. Fast-forward to today, and the Bulls line is more electric assist than not. In a true sign of the times, only three value-priced hardtails exist in its collection. That cross-country race bike in the brand’s beginnings has morphed into the 150mm-travel Copperhead EVO AM eMTB.

FRAME

The Copperhead EVO AM’s front triangle and swingarm are made of 6061 aluminum. It is a mixed-wheel “mullet” bike with 29-inch front and 27.5-inch rear wheels. Bulls offer the Copperhead in four sizes, listed in centimeter seat tube heights like road bicycles. Our size-54cm test bike is equivalent to most brands’ size medium. It has a 66-degree head angle, 75-degree seat tube angle (74 degrees on the larger sizes) and a 465mm reach.

Cables are internally routed through the frame with standard cable ports, but two of the drive unit’s wires are routed through the headset. There is also a water bottle mount inside the front triangle.

DRIVE UNIT

Bosch’s Performance Line CX Smart System powers the Copperhead, producing a maximum of 85 N/m of torque from its electric motor. This is Bosch’s top-of-the-line system and its first to feature Bluetooth connectivity via its eBike Flow app. In this app, riders can tune two of the four modes for assist percentage, power delivery and cutoff speed. The Tour and the more powerful eMTB mode automatically adjust power output based on torque and cadence.

Everything is controlled and monitored through the LED remote switch. This is where you power up the bike and toggle through the assist modes. Light color indicates mode choice at a glance, and five bars show battery level. For those who want an actual display, a variety of options are available from Bosch and can be integrated into the system. There is even an option to use a cell phone as a display, but that is probably not the best idea for off-road trail riding.

crossbar, electric, bike

Paired to the motor is a 750Wh battery pack that’s hidden under a quick-release removable cover. The battery has a six-hour claimed charge time from empty with a 4-amp quick charger.

COMPONENTS

Bulls offers the Copperhead EVO AM 750 in four different configurations starting at 5999. Our EVO AM 4 750 is the top-of-the-line version that’s outfitted with a Shimano XTR drivetrain, BR6120, four-piston/two-piston brakes with large 203mm rotors and EThirteen 165mm-long crankarms. Its rims are tubeless-ready, Bulls-branded Ryde Disc 30 rims shod with a Schwalbe Magic Mary in front and a Hans Dampf in back, both with Super Gravity casings. The cockpit consists of Bulls-branded parts, a Fox Transfer dropper post and Selle Royal Vivo Ergo saddle. The bike should have come with a Limotec A1-Z dropper post, but supply challenges changed that to a Fox Transfer on our test bike.

One unique aspect of the Copperhead is a Bulls headlight and taillight mount that is hard-wired into the battery system. The bike is specifically designed to utilize Bulls’ Monkeylink headlight and taillights. The lights are secured via a cool, magnetic anchoring system and do not come with the bike but are available separately.

SUSPENSION

A classic, FSR-style, four-bar linkage suspension design paired with a Suntour RS19 TRIAir 3CR shock achieves 150mm of wheel travel. Up front, things on our test bike were not to spec due to supply-chain issues. Our bike had a 140mm-travel Suntour Durolux 36 fork instead of the 150mm travel model, which comes with an RC2 damper with high/low-speed compression damping adjustments. Not only are lockouts unnecessary on an electric bike, it didn’t offer any sort of compression adjustments to hold back the performance. Late in our testing, we received the correct fork.

WHAT DID WE LOVE?

As with most electric bikes, the Copperhead flies up climbs. Its suspension is active yet efficient-feeling, and the Bosch motor is powerful. Even though they claim 85 N/m of torque, it feels stronger than that and almost at the level of Rocky Mountain’s Powerplay system, which we reviewed in the May issue. The best way we can describe the feel of the Bosch system is that it combines the powerful feeling of Rocky Mountain’s Powerplay with the smooth nature of Shimano’s EP8. No, it’s not quite as powerful as the Rocky or as smooth as the EP8, but it has characteristics of both.

We used the eMTB mode most of the time, but tweaked the Turbo mode in the app for maximum output when we really needed a burst of power. Speaking of power, Bosch has introduced the Extended Boost feature into the eMTB mode where power stays on for a half-second or so after you stop pedaling to help with technical maneuvers. It’s awesome, and we wish it were available in all modes.

Shimano’s XTR drivetrain is about as good as shifting performance gets, even under loads of electric assist. The lower-end Shimano brakes with a two-piston rear caliper might raise a few eyebrows, but they surprised us with powerful, fade-free performance.

Cornering and overall handling are very good on the Copperhead. It feels planted yet changes directions predictably, thanks in part to the grippy, soft-compound Schwalbe tires and smaller-diameter “mullet” rear-wheel setup. Geometry also feels dialed on the descents with an ideal trail-bike balance that’s quick enough to have fun in tight singletrack.

WHAT DID WE HATE?

Test riders got off to a rough start with the Bulls. First, the battery cover rattled enough to coax one tester to stuff a piece of cardboard in it to quiet things down. A replacement cover from Bulls measured a few millimeters longer and fit more snugly, but the bike is still quieter without the cover installed than with it. We would like to see a cover with some sort of integrated sound-deadening material or actually integrated into part of the battery itself.

Nobody liked the action of the substitute-spec Suntour fork. It was harsh on sharp impacts and not eager to achieve full travel, so we removed all of its volume spacers. Even our 200-plus pound test riders felt an improvement, but it was still a bit too progressive and harsh-feeling for most. Plus, there were times when its 36mm upper legs felt a bit flexy under the weight of the bike. The correct spec fork proved to be a vast improvement. It is smoother, has more support and uses all of its travel. As for the rear suspension, the shock had a tendency to blow through its travel on hard hits. Using the middle compression setting helped but introduced harshness on small, frequent bumps. When we tested this fork and shock on regular mountain bikes last year, the overall performance was decent, but the suspension seemed overwhelmed by the extra weight and power of the electric bike – particularly in the rear.

One of the wrecking crew riders likes a low bar position and was disappointed to see that the remote switch and light wires go through all but one of the headset spacers before entering the frame, requiring wiring disassembly to adjust the bars. We already have mixed feelings about headset cable routing (mostly negative), but this just took things to another seemingly silly level.

Finally, at 60 pounds, the Copperhead has the unfortunate distinction of being the heaviest bike we have tested in years—maybe ever. It is a solid 5 to 10 pounds more than other electric bikes we’ve reviewed, and you feel it, especially when descents get rough and fast. The weight even seems to mute the Bosch power some, because it just feels a little less punchy than on other lighter bikes we’ve tested it with.

BOTTOM LINE

The Copperhead has a lot going for it. Bosch’s drive unit is incredible. The geometry is good, and the rear suspension design is proven; however, the bike’s overall weight and average rear suspension performance hold it back from greatness for hardcore riders. Enthusiasts and recreational riders who are more worried about comfort and appreciate a planted feel and features like integrated lights will enjoy the Bulls. The rest of us need a lighter-weight platform and better suspension to be truly happy.

Review of the Bulls Sturmvogel E Evo

Hey hey, this is Megan with Fly Rides! I want to put a spotlight today on one of the most stylish bikes in our line up right now- the Bulls Sturmvogel E EVO. For those that want to cruise around town, looking effortlessly chic, this bike will check all your boxes.

The Power-

It’s really strong, goes really far, and has a top speed of 20 mph! If that’s all you need to know, you can skip ahead

With ebikes, you want to make sure you have a strong enough motor to carry you along, with enough torque to get you started, and a big enough battery to last you for your longest rides. This bike uses the powerful Brose motor, with 90 nm of torque- that’s a lot! It’s still smooth though, and quiet. The motor is hidden in the bottom bracket shell, right where the crank (pedal) arms attach, which gives it a low center of gravity. Mid-drive motor bikes like these are the most popular on the market these days because the power feels more seamless and connected to the rider’s input. They are also also much easier to work on if you have a flat tire! The Sturmvogel also has a massive battery pack- 17.5Ah / 650 Wh, with the range listed as 137 miles (that would be in the lowest assist level, on flat ground). I’d say for the average rider on varied terrain, you’ll likely be able to go about 60 miles on the lowest level and at least 30 miles in the highest assist level. You can charge the battery on the bike, or easily remove it from the frame to charge it inside.

The Looks-

With its elegant Euro styling, this bike looks super fresh! It comes in a classic soft white color, with cognac brown accents. The white wall tires, leather grips, and leather saddle look great together. The saddle is a little firm, which I do like, but if you want a little more cush for your tush, you could easily swap it out for another- I like the Selle Royal Drifter or the Brooks B17 Pre-aged. If you want to make the ride even softer, you could put on a BodyFloat seatpost- it’s like having rear suspension! The handlebars have a mustache design, which helps you sit up straight for your casual rides. It comes in four sizes- 41, 46, 51, and 56 cm. I’m about 5’5”, and the 46 is just about right for me- but I wouldn’t go any larger.

The bike looks super clean, partly because the battery and motor are so well integrated you barely notice them. It looks like a fixie, but it’s not! See the next section to find out why

The Components-

One of the best parts of going with a company like Bulls is that you know their components are going to be on point. The Sturmvogel has a Shimano Alfine rear derailleur and hub- internal shifting, no messy rear cassette to keep clean! Just like with a traditional derailleur, it works best if you shift when it’s not under load. If you see a hill coming up, go ahead and shift before you get there and ease off the pedals for about a second until it shifts.

The brakes are Shimano BR-M447s, and once you go hydraulic you’ll never want to go back. The levers pull so easily, you’ll never feel too worked with your hands. They are maintenance free day-to-day, you’ll just want to get them checked over every 6 months or 2K miles, to see if you need new pads.

The Sturmvogel comes with built-in lights that run off the battery power- so convenient! The display is easy to use and takes up hardly any room. Just give a firm push up or down to control your pedal assist level.

The Lowdown-

This bike is for the relaxed urban rider, who wants to look fresh on their way to brunch and running errands, and wants a low maintenance, powerful, and quality ride. The best way to decide if you like it, is to try one! Come down to our shop in La Jolla for test rides, and we’ll show you some great options.
