How Fast is a 5000W Ebike. 5000w electric bike

Some Ideas on building a 5000w E-bike

    26 wheel with a 5kw hub motor.

50 mph max on flat ground, to start off with. The power level seems to be capable of 70, but that will be for another time. Overbuilt = durable.

I’d like to be able to cruise at 30mph for 60 miles, just to toss a number out there. I’ll more likely vary between 20 and 35, with the occasional blasts to 50. details about the expected range below.

I’ll be using a pair of Shimano Deore hydraulic disc brakes, 203mm rotors. Though, I might use the Saint model, for its downhill-specific use. I need to be able to stop this thing at 50, because, well, that’s important.

Rider weight is a feeble 135 lbs. Fully built, I am expecting around 200 lbs with me on it.

Terrain is flat, flat, flat. With the occasional 3% grade, except for Clermont and Mount Dora. I will go out there from time to time. I’ll be on pavement 95% of the time, using a hardtail. I’m probably going with Maxxis Hookworm tires and thorn-resistant tubes. Tire choice isn’t chiseled in stone yet.

Orlando is backwards a hell in terms of cycling safety and regulation. Most motorized bikes on the road here are walmart huffy beach cruisers with coaster brake only, rigged with a 50cc gas engine leaking fuel, spattered with dirty exhaust, ridden by a guy with 3 DUIs, at 40 mph in the bike lane.

About the expected range : I used the e-bike simulator to get a number, based on tweaking some custom specs that seemed to be close to my build. I used the:

This is the online store for a factory that produces them in mainland China (god I love the future). I have been seriously considering this kit. This post of my project idea is also a sanity check, before I spend any money. Anyone here would know better than I would:

Is this a good deal? Is this junk?

If I need to call the manufacturer to get more info on the products, what questions should I ask them?

Are the battery specs on par with what I should be using (72V 26Ah) ? I’ll get two of them if so.

Can anyone direct me to a superior product(s) with the same build goals?

Any input is much appreciated.

Yeah,, at 30 mph, he’d be able to pedal up 10% of the power needed, if even that. And he’d need a giant front chain ring to pedal at all at 30 mph.

At 20 mph, he can pedal up at least 20-25%,, At 18 mph, a solid 30%.

1500 wh of battery can get you 60 miles, at 18 mph for sure. That’s 72v 20 ah,, 48v 30 ah,, For really big range you start having to build a frame that carries it.

I built this, to easily carry 4000 wh. But right at the moment, I only own about 3000wh.

That looks like a QS clone, and a Sabvoton controller, which seems like a good combination. It will likely be insanely powerful for a 135 lb rider. You could shave some weight by going with a smaller DD hub like a MXUS 3K-Turbo or even a 35mm Leaf or Edge motor, and still meet your desired goals. Just make sure to get a high Kv motor (11 to 15 RPM per volt) and a 80A 4110 controller. A 72V battery that can output 80A will be the more difficult task. Stick with Samsung 25r cells or LiPo if you can charge and maintain it safely.

Pedaling along at 30 mph would net you about 10% more range. I do it for miles at a time. It does not require a huge chainring. I run a 53/11 top gear, and can easily keep up at my typical 80-90 rpm cadence.

That battery pack from EM3ev would be way better than the one you linked to. And 60 miles would certainly be doable, if you can stay in a tuck on an upright.

At 18-22 mph, I am an eccentric old guy to police, and other road users. At 30 mph, I am a mildly annoying, curiosity. At 50 mph I’d be a threat to their self image, and possibly a terrorist.

30 mph requires 40 wh per nile, so you need a 2400wh battery minimum for 60 miles. Personally I’d use at least 30ah of 24s lipo. I’d pair that with a mxus 4503 motor and a minimum 3000W controller.

My bike doesn’t require anything like that much power. With me pedaling along at 30 mph, I typically see 24 Wh/mile.

This simulation shows my motor, my actual tire diameter, my average battery voltage over a 48 amp hour run, and my actual gross weight, without pedaling.

If you spend a lot of time above 30-MPH, wind resistance will have a major effect on your battery range. Max range per battery will be around 20-MPH.

Hey, thanks for the responses, everyone. I’m sticking with these specs for the build. It’s just the way I want it. Part of the fun will be testing its range capabilities regarding speed, and other factors. I’ll get another, duplicate super-battery when the funds allow. I’m very impressed with how far and well-developed this tech has become. I remember one the the first eBikes at the REI I worked at in Redmond, WA back in 2001.

I once rode a 150cc Vespa up to 50 mph. The wind was ripping the tears (of joy) right off my face. That was an amazing experience, that really stuck with me for 12 years. Out of all things to spend money on, this ebike project is it. I haven’t been this excited about something in probably forever.

Oh yeah, that thing is way better. I need a BMS, so I’ll get a different one from them. I imagine I can get some more Ah out of a customized unit. Thanks for the link!

Insanely powerful is right up my alley. I’ll likely detune it in the beginning. I’d like to have a platform to build on, rather than needing to replace major parts like a motor. But, I’ll look into these, thanks!

I’m concerned about batteries that might explode into a fireball. The LiFePO4 seems to be the best option. I’m also new to proper recharging practices, so I’d like a battery that’s more forgiving, more or less.

That depends on 3 things: when you ride it, where you ride it, and how much respect for the law you have. In my experience with overpowered vehicles, you can play with them quite a bit at the right times and places, along with a dose of self-control. Police around here are more interested in car/motorcycle racing, and the gas motor bike guys doing 40 in the bike lane. I’ve met and talked to many of them, being in the bike shops. You have to have some blatant disrespect for the law in view of police to get stopped. And even then, you’ll have to carry on a bad attitude with them to get into trouble. If you’re some dude on a bike with no noise, who has a happy, cheerful attitude, then no problems. For the most part.

I was thinking of using a Trek 4300 aluminum mtb frame. But, at closer inspection of the slotted axle and torque arms on the motor, I’ll really need a steel frame with horizontal dropouts. 200nm of torque might punish the 4300 too much, lol.

Bacchettas are nice! I don’t want a recumbent for 5kw, though. I know the handling of a hardtail mtb and roadbike well.

Come on guys. 60mph with a hardtail and just disc brakes on mostly pavement

Does pavement have the same meaning as in the U.K?

Not just any disc brake. one that comes equipped on freeride bikes going 50 downhill. Locally, pavement = asphalt. Never gravel, sand, hard-pack dirt, grass, etc, as long as I can avoid it.

If you spend a lot of time above 30-MPH, wind resistance will have a major effect on your battery range. Max range per battery will be around 20-MPH.

Yes, this is true. I imagine it’ll be around 20~30 most of the time. I regularly hit 30 on my road bike many times per ride, so I definitely know what it takes. I’ll probably be pedaling with it the whole time, since I don’t know any other way to do it.

On a recumbent, you wouldn’t need 5kW for the speed you want, but it has been done, more than once, and at least 13 years ago.

Use a QS 205-H50 v3 with an 18 fet 4110 controller, not expansive, very smooth spinning, efficient. and both able to be upgraded to much higher performance if/when you want to.

Saint brakes, at 50 Mph you won’t regret.

Hardtail is OK if pavement is very nice. On mine field streets that we have here, I couldn’t build a hard tail for 50 Mph.

My god, popping wheelies on a recumbent. that’s a lot of torque! Well, don’t get me wrong. Doubling the range for whatever build is an attractive feature. It’s the handling characteristics of a ‘bent that I don’t want for high speed. I just feel like they’re too twitchy. But, that seat would be way more comfy after an hour.

This looks a lot more professional. The link I provided in the 1st post looks like a mimic company that’s jumping on the craze. Usually, they will model themselves after the real deal, who I’ve been trying to find. If this thing is upgradable, then I guess 3kw is a good start. Watching some vids of this power level makes me realize it’s what I’m looking for.

How does this kit look? Anything to change? I can’t tell if that’s the 4110 controller you mentioned. It’s too bad they don’t lace to a 26 rim yet, but no worries. I’ll just ship it off to JB for a build.

This is based on your years of recumbent riding experience?

Picture taken while riding no-hands.

You do know that the current land speed record on a bicycle is now held by a recumbent at 86.65MPH?

I didn’t see the upright streamliner record in Indianapolis, but I did see it race against streamlined recumbents at the State Fair track, in Milwaukee, back then.

The kit is the easy solution, yet a good start. The seller can upgrade, you need to discuss.

Experienced builders do prefer to buy the motor alone, in its best version : qs 205 h50 v3 that means with 50mm magnets, alu stator with extra copper fill and upgraded phase wires. You can find it in ES for sale new qs motor. PM Vito, I believe he still selling it for 273

We use a smaller controller that is neat to mount on the bike frame in full air flow. You will also find threads about them 18fet 4110 controllers in the for sale new section of the forum. They can deliver a lot of current when upgraded to their best, but 5 000w is within the stock spec, and pretty low for both the motor and the controller. I feed well above 20 Kw bursts and they are running pretty cool.

For the rest, throttle, switches, etc. they can be found cheap in a good variety, many sellers have them or you can order with the controller. Wire and connectors for harness, voltage monitors, etc. are found at Hobby King: 8 ga silicon wire and big gold bullet connectors. Many of us are using 75 A Anderson connectors for they are safe and reliable to disconnect frequently.

Good luck with your first build.

Yes, that’s exactly it. I love recumbents (also worked at Catrike), but I don’t have a lot of miles on them. I certainly don’t want to go 50mph on one. I’ve ridden many, either a customer’s tune up or a new assembly. Some were very smooth riding. But that’s still 50 miles compared to 30,000 for an upright road/mtb.

Really? Well, let’s say I wanted to run my bike in the quarter mile. I’d like it to do around 70 mph tops. It’d be neat to go back out there again with something different. Plus, I don’t have the 11 sec beast anymore, so I gotta build something cool. Do you think 5kw is enough to do it? I’ll be using a 17 moped wheel, with probably a 2.25 wide tire. That’s about 23.5 diameter, which needs around 1,000 rpm. How would I achieve that? Is it as simple as using the 304T (11.39kV) running 88V? I know it’s important to have enough torque to push it up to those speeds, too, which I guess is where the amps come into play.

After you contact Vito at QS motor, someone will send you a mail with all the motor spec and the speed of all the winding turn count available. Select the winding that will make your desired top speed in the size of wheel that you plan to use.

Then, 5 Kw is making a bike aggressive enough for most. Above that you need to think about geometry and suspension to build a bike that has the handling characteristics required for that sort of power. Above 10 Kw, it is very easy to build a bike that is dangerous to ride because it doesn’t handle, accelerate and brake neat enough.

Making a blanket statement like, recumbents are twitchy, is kind of like saying Mexicans are murderers, and rapists.

My experience is just the opposite of yours. I worked in bike shops my last eight years of work, and checked out 5K tt bikes I couldn’t ride no-hands.

I never made any record of my rides for the first 25 years, but starting in 1994, when I got my first cycle computer, through 2015, I logged 38K miles on pedal bikes. Two thirds of those were upright miles. I haven’t ridden a pedal bike in more than a year. The last time was returning from the salvage yard, when I junked my car.

Since September of 2011, I have ridden 35,019 miles on electric assist recumbents.

The fastest I ever went on an upright was 44.0 mph, in 1997, on my 1972 Frejus, which I still own. This was on a descent with a tailwind, of course, as I never got over 30 mph under my own power on a bike in my life. I have done 40 mph many times on uprights, and recumbents, and the uprights always felt terrifying at those speeds, with my chin on the bartop, looking out the top of my watering eyes. The recumbents always feel rock solid, as I have my head up, and I am firmly planted in a real seat, going feet first, instead of perched on skinny rail, with my head out front, below ass height.

The fastest I have ever gone on a bicycle was 46.5 mph on my RANS Screamer, back when it was still a pedal tandem. It was totally relaxing. no drama at all. Now that it is a DD electric single, it has never gone over 36.5 mph, thanks to the back EMF above it’s 32 mph top speed. However, my Linear mid-drive sees 40-44 mph on most rides, since it freewheels.

Hell, I even went 42.0 mph, on my rowbike, on a descent.

and felt much safer than on an upright.

How Fast is a 5000W Ebike?

A 5000W ebike is a great choice for those who want a fast and powerful bike. They are able to reach speeds of up to 50mph, making them one of the fastest bikes on the market. However, with this speed comes a higher price tag, so be sure to do your research before purchasing one.

A 5000W e-bike is considered high-performance and can reach impressive speeds, but the actual speed depends on factors such as rider weight, terrain, and motor assistance.

Assuming you are asking about a standard 5000W ebike, they can reach speeds of around 50-60 mph. This will vary depending on the weight of the rider, terrain, and other factors. Generally speaking, though, a 5000W ebike is one of the fastest types available on the market today.

How Fast Is A 3000W Ebike?

The speed of a 3000W ebike can vary depending on several factors, such as the weight of the rider, the terrain, and the condition of the bike. A 3000W ebike is generally considered to be a very powerful electric bike that can achieve high speeds.

A 3000W ebike can reach a top speed of around 45-50 mph (72-80 km/h). This is much faster than a traditional pedal bike and is comparable to the speed of a small motorcycle or moped.

It’s worth noting that the maximum speed of an ebike is often limited by law in many countries, so it’s important to check the local regulations before riding at high speeds. It’s always important to wear appropriate safety gear and to ride responsibly, regardless of the speed of the bike.

What Is 5000w In Speed?

It’s difficult to give an exact speed for a 5000W electric bike as it can depend on various factors such as the weight of the rider, the terrain, and the type of bike. However, a 5000W electric bike is considered to be extremely powerful and can reach very high speeds.

A 5000W electric bike can reach speeds of up to 60-70 mph (96-112 km/h). This is comparable to the speed of a small motorcycle or scooter and is much faster than a traditional pedal bike or even most standard electric bikes.

It’s important to keep in mind that the maximum speed of an electric bike is often regulated by law in many countries, and it’s important to follow local regulations and safety guidelines when riding any bike, particularly one with high power and speed capabilities.

How Fast Is A 5000W Electric Scooter?

The speed of a 5000W electric scooter can vary depending on various factors, such as the weight of the rider, the terrain, and the type of scooter. However, a 5000W electric scooter is generally considered to be a very powerful scooter that can achieve high speeds.

  • A 5000W electric scooter can reach a top speed of around 50-60 mph (80-96 km/h). This is comparable to the speed of a small motorcycle and is much faster than a traditional kick scooter or most standard electric scooters.
  • It’s important to keep in mind that the maximum speed of an electric scooter is often regulated by law in many countries, and it’s important to follow local regulations and safety guidelines when riding any scooter, particularly one with high power and speed capabilities.

What Is The Speed Limit Of An Electric Bike?

The speed limit of an electric bike can vary depending on the country or state in which it is being used. In the United States, for example, electric bikes are classified as either Class 1, 2, or 3, and each class has a different speed limit.

  • Class 1 electric bikes are equipped with a motor that provides assistance only when the rider is pedaling and the motor stops providing assistance once the bike reaches a speed of 20 mph (32 km/h).
  • Class 2 electric bikes are equipped with a motor that can provide assistance even when the rider is not pedaling, but the motor stops providing assistance once the bike reaches a speed of 20 mph (32 km/h).
  • Class 3 electric bikes are equipped with a motor that provides assistance only when the rider is pedaling and the motor stops providing assistance once the bike reaches a speed of 28 mph (45 km/h).
  • It’s important to note that these speed limits are for electric bikes that are being ridden on public roads and paths. The speed of an electric bike can be higher than the legal limit if it is being ridden on private property or in off-road situations where there are no speed restrictions.

Conclusion

if the bike is being ridden on flat ground with no wind resistance, it could potentially reach higher speeds. If the bike is being ridden in hilly or mountainous terrain, or if there’s a strong headwind, the top speed will be lower. Ultimately, it’s important to test out your own bike to see what its top speed is.
