electric bike vs gas scooter ?

The electric, unquestionably. Super torque, which is essential to a drag race. You'd be able to do even better with a gearbox, though.
Pretty much the best thing you can have in a drag race is a series wound motor. Speaking of which, I wonder how much torque something like a WarP (configured in series) has. Foot-ton range is my guess.

No way. Maybe at lower voltages.
Wasn't there someone on here that geared his for something like 60mph?
I tested my BD36 in a 26" rim at 48V and it will do over 30mph no problem (I think).

A long time ago, I took my Vego scooter to a Goped racing event. I drag raced a bunch of hopped up Goped scooters. I totally dusted all of them, except a 65cc. By the time I raced him, my batteries were getting weak 
. Off the line, gassers don't stand a chance, but depending on gearing, they might have a higher top speed.
. Off the line, gassers don't stand a chance, but depending on gearing, they might have a higher top speed.With that reasoning you may as well use a 600c motorcycle and call it 50cc. If it goes faster then 32km/h it falls in moped category, faster then 50-ish and it's a motorcycle, so on. In the same line of thought, comparing a motorcycle that is insurable/plateable to one that doesn't even have a remote glimmer of a chance seems rather pointless.Link said:
It's like time my bro & I left a location jsut about spot on the same time, he was on his motorcycle and I was on a vanilla bike. Without being warmed up I out-accelerated him quite easily, stayed ahead for the first ~15 meters. If we would have been both on fairly similar vehicles such as bicycles or motorcycles or some such, there could have been something to learn say from gearing or whatever.
Bro's motorcycle pretty much as seen here btw:

Ah, I was thinking you were coming purely from a performance standpoint. My bad. I suppose things DO get trickier if you take into account what actually constitutes an "electric bicycle".

Now that I think about it, what prompted you to make this topic? Got something in mind 8)?

Dude, I swear if I knew someone with a gas scooter I totally would.
I sincerely doubt it would last long if I were to do it, but I hear the BD36 is rated to 96V. That's over 45mph in a 20" rim 8).

If you keep the armature current within spec I bet it'll live quite a while at that voltage. Prolly a bit more efficient too. The brush wear rate might be interesting though

Well, I fried my current controller in a reverse polarity situation ( :x / 
), but the electronics look okay. The motor only got mildly warm at the controller's exact amperage limit of 33.4A, and, given my riding style and rim size, I'm betting it was at or close to that limit all a LOT. I'm getting a new one, but I'm thinking I might turn the fried one into a 4110 or similar supercontroller.
Oh, and you can bet your ass that I'll eventually at least TEST at 96V 8).

I happen to have a Honda Lead90, 90cc 2 stroke !It's going to take a fair amount of watts to outperform this scoot.. but i think my X5304 powered BMX at 72v 40 amps will be close up to aprox 40 mph.. then it's a factor of how long the battery pack can sustain 40 amps without melting down.

Hmm, I can say for sure that my puma driven KMX can beat 5 testosteroned youths on 50cc scooters (load pipes and all) to 35 mph. Last summer a "gang" of youths took me on on the local "Drag Stip" (the "strip", a short stretch of road on brighton seafront, made famous in the film Quadrephenia, and often used for the brighton speed trials). THey were laughing as they all drew up beside me, but swearing when I beat them to the end of the strip and ducked onto a bike path to avoid the traffic where they floundered

Awww, boy. It's on now!
With a few quick calculations, I can approximate that a BD36 in a 20" rim at 96V will just do 50mph. And, if what I've seen at 48V in a 26" is anything to go by, I could probably get up there in less than five or six seconds 8). Assuming I don't do a wheelie and flip over backwards 
.
Gotta find some good spokes for a 20"...

Or spin the tire...
I have some affordable motorcycle spokes, let me know exactly what length you want and I'll check what I have. You will probably have to bore out the holes in your hub for these fatties tho.

Burnout, burnout 8)!
Bore out rim = no problem.
Bore out HUB = questionable...
I don't have a 20" on me to check the length, though. I could afford a whole other bike right now, but I'd rather keep at least $500 in the bank at all times. Gotta wait till Friday for my paycheck...

Grah! I know! They're so hard to pick out, though. Too many models. And I don't need anything too great, but 30fps DVD quality would be nice (which seems to be fairly common). According to an issue of Consumer Reports (read while I should have been working), the Canon PowerShot 550 is about the best you can get for the money. I think I might go with that...

Indeed, but so could an system with an X5. Overvolting would be the same as adding a turbo: forcing more power into the engine. Fatter wire and better batts would be like chopping the exhaust. You could blow cold air (or even liquid CO2 or something) into the motor to keep it cool. Twin engines? Add another X5 8).
Anything else I'm missing? (probably)
I take it your not aware that you're preaching to the choir there. :lol:
