How To Build An Electric Motorcycle – Complete Build & Test Ride!



How to build a FAST electric motorcycle. Get the plans:

In this video I build an original custom electric 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).

  1. Yang kaya gini yang harus banyak subscribe nya channel yang penuh inspirasi dan kreatif👍👍👍

  2. Awesome hope to built one from your plans or a reverse trike like tri magnum, what's the top speed and range thank you

  3. Amazing skills … from the moment i have completed your video … assumed you my GURU … one day i will meet you in person.

  4. OFFICER: Papers and ID, Sir!

    This Man: actually officer it's a home made, so…. I don't have papers…

  5. Just think guys, this is his first design. Just wait until he improves it even more. I wish him all the luck in the world and hope to see him develop and grow a company.

  6. Man!!!! It's amazing. You are a genius. I'm from Argentina, here that's imposible. Congratulations man!! Do you make it someone whit traditional enginee?

  7. Calling this “mind blowing” is an understatement. I rank you top 5 of all times on YouTube without a second thought.
