Electric motorbike racing

[Jonathan]

Judging from the videos of the acceleration of the Tesla car / youtube/ i can only imagine what is the acceleration of electric bike with a nice motor.

The difficulty with a bike is the tendency to wheelie limits the acceleration obtainable, but still the acceleration will be substantial. We have a fixed gear ratio, so for example if we gear it for a top speed of 160mph we will, according to my calculation,easily get 0-60 in under 2.4s and 100mph in about 4.2s. Compare that with these figures:

Time[note]	Make and model	Year (model)	Time (seconds)[note]
2.35	Suzuki GSX-R1000	2005	2.35[1]
2.5	Yamaha VMAX	2010	2.5[2]
2.6	BMW S1000R	2014	2.6[3]
2.6	Kawasaki Ninja ZX-14R	2012	2.6[4]
2.6	Honda CBR1000RR (Fireblade)	2008-2014	2.6[5]
2.7	Ducati 1198S	2010	2.7[6]
2.70	BMW S1000RR	2011	2.70[7]

I see that more difficult done with bikes, cause petrol bikes accelerate really fast. However not having a gearbox will really help.

Yes - if we gear it for a torque of just over 1000Nm at the rear wheel, we'll have that torque available all the way up to 180mph.

What is the weight to HP of that bike?

Around 1000W/kg. Compare that with these:
