Building An Electric Streetfighter Motorcycle - Complete Build & Test Ride!

Publicado em 17 Nov 2020
In this video I build a custom electric streetfighter motorcycle. Plans for this project are available at the following link:
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 over 100 ft-lb of mid-range torque, and only weighs 300 lbs. Top speed is limited to 115-150 kph depending on the system voltage, but it boasts more torque than most 1000cc bikes to produce white knuckle acceleration at legal speeds, so you can still have fun without the risk of getting a speeding ticket, or worse. In fact, unless you're a pro rider with great throttle control on one wheel then you'll probably want to use the controller program to lower the torque to 25-50% for the first few rides.
Specs and links for electrical components can be found below.
Bike specs:
Power: 12 kw/ 24 kWp, 32 hp gross
Motor: QS273 70H brushless hub motor
Battery: 74V/4.3 kWh Li-Po
Range: up to 100 km's
Top speed: ~115 kph (71 mph) @ 72V, 150 kph (93 mph) @ 120V
Max torque: 350 Nm (258 ft-lb)
Controller: Kelly KLS72601
Wheelbase: 55" (140 cm)
Rake angle: 26°
Trail: 4.9" (124.5 mm)
Turning radius: 72" (183 cm)
Weight: 300 lb (136 kg)
Front suspension travel: 5" (130 mm)
Rear suspension travel: 8" (203 mm)
Front tire: 120/70-17 Shinko 705
Rear tire: 180/55-17 Metzler Karoo Street
Electrical components:
72V motor
KLS72501 controller
72V/400A contactor
LiPoFe4 cells
24S (72V) LiFePo4 BMS
72V-12V Converter
12V horn
12V turn indicators
12V/18W LED bar lights
12V LED brake light
Sicass Racing handlebar switch
Music: 'Dark Epic Hybrid Rock' by Pegasus Music Studio
ROI breakdown:
Cost of electric bike build = ~$5000 total
Nominal battery capacity = 4.3 kWh
Life span of LiFePo4 cells = 3000-5000 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
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).
Most people only travel an avg of 45 km's per day back and forth to work or school, so as a daily commuter a person can expect a bike like this to pay for itself in 10 years or less. But the great thing is, the more you drive it, the shorter the payback period. Those who travel farther will get a better return on their investment.

  • I'm getting a lot of comments about how to register a custom built vehicle, so I'll address it here as best as I can. The answer is, it depends where you live. It's definitely possible in most of North America, but not everywhere and it can be more difficult in some places than others. But to give you an idea, here's a link explaining the process in my home province Ontario (Canada): Specs for the bike are in the description as well as a detailed CBA outlining the return on my investment in this project. Plans are available for those who are interested at the following link: Time stamps: Building the chassis - 0:00 Making the fairing - 10:16 Installing the electric drive system - 18:28 Test ride - 26:28

    • Sir make a same model of a bike and please try to deliver on India and my country is Manipur imphal west

    • Genius .. I’ve tried using styrofoam before for molds but it didn’t work since I used resin with the fiberglass cloth never thought about using epoxy 👍

    • Can I have that I really like your work

    • How much this bike costs

    • @James Biggar Sent you an email inquiring about having one built.

  • Amazing build..

  • What is it's price?

  • Beautiful build mate. I'm impressed how quick and dirty yet precise you crafted that bike. Very high skills. Cheers!!!

  • That is so sick, and what an inspiring vid. Thanks for sharing ✌️☺️

  • Quiero una 😳

  • Awesome job, looks great. So what's the top speed and how many miles per charge can you get?

    • Thanks. Top speed is 150 kph (93 mph) and I get ~100 km's per charge. The battery that I used is a recycled 4 kWh LiFePo4 from a previous project. There's lots of room to triple the capacity with li-ion if a person wants, but what I've got serves my needs fine.

  • First time I've seen that pvc foam board, now I know what I can use to make a new seat base on my trike.

    • It's good stuff. I see boat builders use it all the time and thought I'd give it a try. Could've used thinner stuff, it's more rigid than I thought. But it's great for stapling the cover on. Much better than fiberglass, no mess either.

  • Loved every second of the build she’s beautiful 👏👏👏👏👏

  • 30:07 Heck yea!!! we in the future babyyyy

  • FANTASTIC! “His hands are licensed as precision CnC machines” Would you consider a Golden Motor 25KW BLDC (water cooled) with an 18650 battery pack of 32S40P (any shape/distribution you like) on a custom stretched cruiser-commuter frame with full suspension?

  • 😲 wow

  • Nice😃

  • No faffing about, straight to work. Awesome.

  • Te doy tres harina pan por la moto.👌🏻

  • U are amazing!! How much did you invest in materials? did it cost you a lot?

  • This isn’t what we meant when we said diy

  • Incredible, Vmax, autonomie ?

  • I don't know how many people got around to watching the entire video, but, I noticed that he put in the video that he had set the torque at 16% of maximum which means that based on his calculations of 16% or 40 foot pounds of torque, the bike is capable of around 250 ft pounds of torque. Go ahead and let that part sink in.

  • Awesome bike men. Where did you bought the motor and the battery?

  • Bike startup sound was amazing!

  • DIY on fucking steroids

  • Speed, acceleration, & range?

  • love the sound XD

  • Nice Bro 👍

  • What if I want to use a separate motor? like no hub motor? so what changes should I bring to the design? Please let me know

  • This is one of the coolest things I have ever seen!!!!!

  • absolutely brilliant...whats the top speed and how much it costs you in total?

  • Bro, you're so cool.😄

  • This is the guy you'd want in your group in a zombie apocalypse

  • The overjoyed armchair progressively care because windscreen functionally bump regarding a sassy pants. stingy, hurt jeff
