I think all the empty space makes for a visually interesting bike :)

Agreed.  Please don't play around with too much with the existing aesthetics.

no worrie, it will remain as is.. until i discover how much aerodynamic can help to lower the E.T. ;)

And YES i confirm that machine is a true WHEELIE machine!!

at 75% torque setting the front end lift to about 5 degrees sustained while it accelerate like a TESLA !

First REAL test soon!

i'm installing a cycle analyst on it to have real time visual on the kW, SOC and voltage. it will also datalog all info just like the Sevcon does also.

I will also install a VBOX to have 1/10s fast sampling GPS speedometer.

That beast is QUICK !!

You should put a teddy bear with old time airplane goggles in the empty frame.  That would be hilarious!

Going by the pictures there are still a few low hanging fruits you can shave off to save weight and improve drag. For example I don't think you need indicators at a drag race ;D

Doc,

The sticker says 70 kW.

Is it wrong or just early? : )

Yes the sticker is good, that battery can deliver up to 70kW and has been tested to that power level but the sevcon size 6 is limited to 50kW so the bike is 50kW.... from now!.. untyil i beef up that battery and install dual size 6... but this might be only next year.

Actually at 80% torque this is a true wheelie machine! and at 75% it make a perfect 5 degree Wheelie from 0 to 120kmh!  but that is with the 132T and 30T. Harlan sent me the 98T  and belt kit . i'll use these to increase powerband and speed and make me able to set max torque to 100%

with 50kw(67hp)  and total weight of 360 pounds this will make a ratio of  5.37 pounds per hp witch is very close to the Ford Shelby GT500  at 5.8

Are you including your own weight in with that 360 pounds?  (I think I'd leave it out, if so).

This is a really cool machine. Ive pulled 62kW indicated on a Cycle Analyst with a maxed out Size6 controller.  Be curious what you pull at 100%

This would seem to be a case where the weight of the jockey is even more critical than that in horse racing.  Think what the weight/power ratio would be with a well-trained teenager who might only weigh 100 pounds or so.
