In this video I build an original custom electric streetfighter motorcycle from scratch for less than HALF the price of an equally sized ZERO S. This aggressive looking streetfighter uses the same 24 kW (32 hp) drive train as the previous Cyber Trike project. Though equivalent to most 300cc street bikes in overall power, this little monster boasts a massive 250 ft-lb of max starting torque and only weighs 300 lbs. Top speed is 150 km/h @ 120V. Full specs and a cost benefit analysis for the build can be found below.

ROI breakdown:
Cost of electric bike build = ~$5000 total
Nominal battery capacity = 4.3 kWh
Life span of LiFePo4 cells = ~5000 cycles
Range per charge = ~80km @ 80% DOD (up to 100 km @ 100% DOD)
Grid energy cost = $0.12/kWh
Cost per charge (100 km) = 0.12 * 4.3 = $0.52
Cost per km for energy = 0.52 / 100 = $0.005
Avg price of gasoline in Canada = ~$1.00/ liter
Energy in 1L of gasoline = 8.9 kWh
Fuel economy of the most efficient petrol bikes = ~60 miles per gallon, or 25.5 km per liter
Cost per km for fuel = 1 / 25.5 = $0.04
Electric bike energy cost savings per km = $0.04 - $0.005 = $0.035
Savings per charge/cycle (80 km) = $0.035 * 80 km = $2.80
Payback period based on full cycle charges = $5000 / $2.80 =
1785 cycles
OR
Savings per day based on driving an avg 40 km per day as a daily commuter = $2.80 / 2 = $1.40
Payback period = $5000 / $1.40 = 3572 days, or 10 years. 5 years if driven 80 km per day.
It's clear to see that an electric bike like this is a sound investment for nearly anyone who can build and ride (provided laws in your area allow it). Based on battery cycles - which is the most important thing because it will need to be replaced eventually and it is the most expensive component by far - this bike will pay for itself entirely nearly twice in fuel cost savings before the battery needs to be replaced, provided that it's maintained and charged properly (ie don't discharge below 80% DOD, don't store, operate or charge above or below the manufacturer's recommended temp., etc).

  • Get the plans for this project here: renewablesystemstechnology.com/electric-streetfighter.html

    • What was the total cost bro, without adding labor cost.

    • @Rohit Kr. Mahaur ya same thinking

    • Price?

    • Can you make.. Toy car....gor baby.... Thnks for everything....

    • James....I’m sure you’ve been asked this before, 1000’s of times but...I’ll play ignorant and ask. What would you sell this bike for? Don’t need you to build another one....just “THIS” one. I’d be curious to know what figure you had in mind. If you feel more comfortable emailing me, I can send you that as well. Awaiting your response.

  • where are you buy a silicone epoxy? Please. I want to known.

  • What type of welding mechine he use

  • Were is the motor

  • I am from India 🇮🇳 nainital I love your bike you made, you are genius I love you man it's very curious and interesting to watch this video really I love this bike.. You are awesome. I am dreaming this bike now. 😊

  • Hiii dude love you from India 🇮🇳 Can you tell me how much it cost to build this bike at home

  • Fastest welder in the West

  • This guy is a damn genius

  • Totally cost

  • Süpersin

  • Very good

  • So cool ! you are super hero, just amazing !!!!!!

  • Получил колоссальное удовольствие от просмотра🔥👍

  • You are so talented... Respect 🙌

  • Just one word: wow!

  • This is a cool bike (awesome work) but it won't get adopted by the Sons of Agony/ Hells Angels type biker clubs. They need lots of attention the "Hey, look at me thing" (and an intimidation factor) when they roll into town. Maybe you can add on speakers that have a looping sound track of a gas fired Harley to attract that crowd. That way the bike can get the green energy movement fanatics off your back - and be intimidating at the same time.

  • Hard work is the key to success.I appreciate his work.

  • cyberpunk meets tron! xD

  • Incredible 😮

  • tests her maximum speed

  • Очень тихий, ему нужно усилитель с динамиком, что бы звук выхлопа выдавал, а то другие водители не будут слышать, как ты едишь!

  • Great skills! And i like the dog😊 much love and respect from Germany

  • Speed

  • so sick!!!

  • Seriously? 🤩

  • After he sprayed i guess the body looks different

    • Psych, I failed, gave up and went out to buy a new custom fairing at the local supermarket. They wanted me to pay with chickens, but all I had was a box of nails. We made a good trade.

  • good job i think i try your plan in my home

  • Come to Nepal where electric bike cost 32k dollars....name yatri search it

  • How much money need to buy this bick??

  • Got to love the torque curve of electric motors, instead of revving at somebody at the light to let them know you want to race you just lock the front brake and slowly spin the rear wheel while maintaining eye menacing eye contact.

  • I think you should collab with ramy rc.. He is excellent with molding and make body part... But this is a masterpiece,, great job man!!

  • I want to buy this bike

  • Price of India

    • $12.6 trillion.

  • Very nice

  • looks like a bike from total recall

  • yatri xa ta broo

  • He can sale this project to a motor company

  • so damn quiet.

  • I like how the airflow can cool the electronics

  • it makes a really funny sound when he was cutting the styrofoam 🤣🤣

  • Love it. Want one.

  • How many is moto's kilogam ?

  • Great job, it looks AMAZING. Keep building beautiful machines like this. Maybe I missed the specs on too speed and 0-60mph acceleration. What is the performance figures like?

    • Thanks. Specs are in the video description. Performance is very similar to a Zero S except the top speed for mine is 5 km/h slower but it has ~twice the starting torque to play with (>200 ft-lb) - not that it's needed anyway, I've got it tuned down in the controller to a noobish 40ft-lb but the 80 to 90 that the Zero produces is all anyone needs unless they have brass balls.

  • Nice job , i dream with it this some day , congratulations fron Brazil man.thanks.

  • Bravo... Rien à dire.

  • Очень хороший инженер

  • This is cool but where is the Motor (engine)?

    • @James Biggar Thanks bud. This is so cool.

    • LOL, look close. If you can't find it, read the video description.

  • I like it

  • Brands: New motorcycle out now! This guy: D.I.Y

  • All brand’ ceo really dont like this man

  • Dude... go on Amazon right now and buy two Samurai swords to strap to your back.. You can't ride this bike without two samurai swords.

  • Huge Work man, u killed the game. Greatings from France!!

  • Nice bike motor

  • This was like hitting elon musk with a rock! Total respect! I am ready to buy your bikes...

  • You worth to receive like for this awesome video!

  • Well done, great bike

  • That is the coolest looking bike I have ever seen... would take that over a production bike every time... what a skill! That is AWESOME! Great job, my hat goes off to you!

  • сталь пластелин М3?

  • I want buy this bike

  • you are very creative. But why do not you instruct the engine transmission and sprocket assembly instructions

    • Its direct drive....................

  • Bro! 👍🏼

  • جميل جدا ورائع الي المام وبالتوفيق ان شاالله ❤️❤️❤️

  • Can i buy it..?

  • then why big e bike company is charging so heavily ???

    • Running a company and mass producing stuff like this takes a lot more 'behind the scenes' work than what a personal project like this involves. Mass producing involves buying and/or building expensive infrastructure to match production capacity to consumer demand. This involves finance companies and rallying investors to provide capital to create the systems needed - investors and financers who expect a net return on their investments within a reasonable payback period. Like most things (such as solar panels and wind turbines for example), when the investment produces a return for the lenders to pay off that debt and the overhead costs decrease, so does the price of the product. It's just a matter of time.

  • James I am so impressed design,fabrication, glasswork,even bloody upholstery. Fantastic skill set sir I crave the day I would commission you to build my bike Only one condition to learn some of those skills also. Honestly one of thee most impressive videos I've ever watched on MRlevel in years.👊

  • This is good don't buy bike make your own superbike ❤️

  • Another level 💯

  • Did controller program allow for regenerative braking?

    • Yes. Specs are in the video description.

  • Very nice bike plz full parts rewind

  • big fan boss👍👍👍👍

  • Is it street legal? Just wanna know, plz.

  • How many cost in indian rupees

  • Great job! next time a lighter weight alu frame and maybe it is possible to 3D print the body parts? What a work!

    • @James Biggar thanks for explaining, makes a lot of sense.

    • Thx! How much difference do you suppose 4-5 lbs less sprung weight would make? My own body weight shifts that much every week lol. Aluminum is weaker, so more material is needed to compensate. That's why most aluminum sport bike frames weigh in at 25-30 lbs. Mine is 30 lbs. Most custom street bikes still use steel not only because it's stronger and cheaper but it's more flexible which gives the rider better feedback and helps the tires keep a grip when cornering because the suspension is at a less than ideal angle to the road surface to work as efficiently as it would when a bike is perfectly vertical. Aluminum is only really needed for performance machines whose riders are hauling iron balls and trying to shave a few tenths off their lap time. They incorporate expensive suspension systems and spend a lot of time tuning them to suit the more rigid aluminum frames. Quick math shows that the benefit for me is maybe 2 km's extra range per charge lol. Not worth the $ I'd have to spend on material or an expensive TIG to work it. Another thing to consider is the hub motor. More sprung weight in the wheels isn't really a good thing either. It's a great motor, but its weight needs to be compensated for in at least two ways; 1 - a stronger suspension, ie: increased spring rate, and 2 - more sprung weight to maintain a proper sprung to unsprung weight ratio. The suspension works with the bike's sprung weight (the weight supported by the suspension only) to keep the tires snug to the ground when going over bumps. When that ratio is off, the suspension doesn't work properly and is almost impossible to tune correctly. It'll be too soft or too stiff, causing damage to the bike and/or yeeting the rider into the trees. Less weight in the frame means more weight needed elsewhere to maintain said ratio. That could be done with the battery, but then we're back to engineering even more weight within an aluminum chassis, which means even more material is needed (solid cast or thicker tubing). It's like a negative feedback loop. There will always be a compromise somewhere, exactly where will depend on the owner's riding style and needs. 3D printers are overrated too. Don't get me wrong, they have their place but are not a cure all. Stumpynubs just uploaded a video talking about this. Regarding CNC machines, but the same idea: mrlevel.info/two/nGSid3ieZIqZgGg/vhi-i A hobby machine would take ages to print this fairing, and ages to print replacement parts if/when needed. Well, days, but would seem like ages. I created the molds and fairing by hand in the same time it would take to print with an affordable printer, or less. If I need a replacement part, it's simply a matter of spending 10-15 minutes layering and casting in the mold, then wait ~1 hr and it's ready to sand vs 2 or 3 days waiting for a print which needs to be worked by hand afterward to get a decent finish anyway. Hobby printers can be really convenient for the avg Joe to own but save time only in the right circumstances. If you have the skills to do something, then it's usually best to do it yourself unless you're mass producing or just having a bit of fun printing a small part for a tool or your kid's toy. To mass produce with 3D printing, a production printer is needed to keep an appropriate pace. This would cost tens of thousands. Not a good choice for someone who only planned on making one of these ;) I have 4 motorcycles already, I don't need anymore lol. I've moved on to building 4 wheeled vehicles now.

  • Will you sell it

  • cant help but think about where all that styrofoam dust will end up

    • I dumped it in the tributary in front of my home. It'll make its way to the St John river, and eventually the Bay of Fundy where it'll make the long journey around S. America, pass through some marine life along the way and join its pals in the great Pacific garbage patch after a few months.... Actually, no. I'm a building contractor. Limiting waste and recycling is absolutely essential to my job in a growing industry that's attempting to move away from being totally reliant on limited natural resources. A large portion of our building products are made with recycled materials, from OSB chip board and MDF fiberboard to foam boards, metal roofing and vinyl sidings. It's necessary. We can't lug anything to a landfill unless recyclables are sorted and separated (you won't hear that in the media, though). But why lug it anywhere to begin with when I can still use it? That foam made great loose fill attic insulation while saving someone $ and keeping itself out of the recycling plant without being dumped in the environment. Better than fiberglass, and easier on my lungs. I can't help but think what goes through the mind of someone who assumes the worst about another trying to do good. Contrarianism doesn't work here, bud. If you're trying to find a flaw, you're going to have to do better than that.

  • Brutal my man

  • Better than the YATRI !!!

  • 👀👀👀👍👍👍

  • This bike by how many ?

  • Indian price

    • 2300 chickens

  • i want to build this but i don't have the welding equipment or the skills to make the frame myself, does anyone know how I could go about doing this? would a shop be able to make this to spec?

  • Can you build the bike from Akira?????

  • my dream, thanks for video and cool machine

  • Epic!

  • Genius.

  • I love your videos and I'd love to see more if there's explanation from the engineering perspective

  • สุดยอดครับ 😍

  • Hello your model is truly inspiring. We are a group of college students working on the same concept can you please mention the source and specification of the products you used . It would be a great help

    • Check the video description.

  • ʢ∩_∩ʡ乃

  • This guy can walk into a scrapyard and drive out in STYLE.

  • Parabéns pelo seu projeto vc e excelente no que faz,parabéns 👏👏👏👏👏👏👏👏👏

  • amazingggggggggg!! Next step is to made it totally in Aluminium!

    • Thanks. Spend tens of thousands on molds to shave 5lbs off the weight of my personal street bike? Lol, no thanks. This bike is done, I own 4 already, I don't need any more lol. Besides, aluminum frames are not as light as laymans like to think they are. Aluminum is weak compared to steel, ergo, more material is required to achieve the same strength, ie: solid cast or much thicker tubing, otherwise an aluminum frame won't withstand the same forces as a steel frame for the same length of time. Aluminum isn't flexible either, while steel is. Some flexibility in a chassis is desirable (vertically) for increasing grip on the road while cornering because the suspension is at a less than ideal angle to the road surface to work as efficiently as it should. This is a feature often lacking with aluminum frames which are typically reserved for competition bikes whose riders are looking for better lap times with a slightly lighter chassis. My steel frame only weighs 30 lbs. Almost all aluminum sport bike frames weigh 25-28 lbs. The weight difference is inconsequential for 99% of circumstances. Unless I'm a pro racer looking to shave a 1/10th of a second of my lap time or add an extra 2 km's to my driving range, then aluminum would be an expensive, unnecessary choice that might actually make the bike more dangerous to ride. Hence why the majority of street bike tube frames are steel, NOT aluminum. Do the math my friend. Cost benefit analysis is important.

  • Just wow man

  • ʢ∩_∩ʡ乃

  • Kieber bike, perfect!

  • Bende istiyorum bundan

  • great work ride safe man !

  • Respect and salute for the hard work and effort you have put on that master piece. Most of the people like me dream to have an electronic motorcycle, you just built one from scratch. And for the haters you wished you had that beauty too

  • 👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼

  • Engineering at its best
