I find the bike so underpowered after riding around more powerful bikes for years that I forget it even has modes.. I just leave it in the "sport" one, and modulate the power with throttle like every other bike. In the parkinglot I wish it had a clutch because it would let you do tight maneuvering that it is incapable of at the moment.
There would be more benefit to get a left rear brake lever and load the motor against the rear brake, then launch it...
Ive had many conversations about clutches on a bike like ours, as the next project up is my Electricross fx 1 brick version I want a clutch to bunny hop it. Im going to rear brake on that bike instead of a clutch because
1.no clutch is going to hold up to an electric motor, yes a two stroke 250,500 might have more power but the level of torque at very low rpms on an electric motor will destroy a clutch. I mean you really need a clutch of around sport bike caliber, for my application thats just not what i want (aiming for as ligt as possiable) so im not ruling it out, there is step two though...
2. (Disclaimer: Just the way i would do it assuming you could get over step 1.) there is not a good way to control the motor over reving when the clutch is engaged, it would require an emmense amout of programming. You would have to limit the rpms to 1000-1500ish (start at 500 and work your way up on a dyno) soon as you engage your clutch (using a different throttle map every time you bring in the clutch lever transitioning from one to the other) so even if you floored it, you would, and never could overspeed, if you could rev the motor no load to 6000rpms its going to go to 8k plus easily and man you better hope you have a good motor Not to mention there would be no "feathering", and then technically You are making a a projectile, with 2 wheels
I wanted something that would just spin tires (starting slides) as my fondest memories "motorcrossing" more stunt riding with my feet over the handlebars on a little pit bike, drifting alphabet letters
3. im sure theres one or 2 more im forgetting about
