What acceleration have you achieved?

[mnplus1556]

hello everybody. i am curious as to what kind of acceleration y'all have seen on your ebikes. post your numbers here and lets compare! oh and to keep it simple how about we all used the same units? meters per second squared how about? (m/s^2). if you need equations to figure out what your acceleration is, i can post those too. happy winter riding everyone

Threw my bike off the pier and got -9.8 m/s^2

Sorry.. I have no equipment to test, although a smartphone could probably do it easily.

Hasn't been a popular Electric Vehicle Technology subject on this forum, but that could change.

There are smartphone apps that will use the onboard accelerometers to measure your car's acceleration. I don't know if it will work for a low end speed, like 30mph, but it might.

The acceleration of my fast e-bicycle is only limited by how close I'm willing to ride the edge of catapulting into the air. Even at 60mph I can't go WOT.

No amount of additional HP/Torque would make me accelerate faster 0-60mph, it could be done only with a longer wheelbase or moving center of gravity lower and more forward. The bike is already longer than a Hayabusa (which is a strong negative impact on it's handling), and it would be a lot of effort to get COG lower. For the drag event in WA (where it will be using 2 x Sevcon size6 controllers) I will likely add another foot of swingarm, but it will feel like shit to ride at that point.

0-60mph is in the mid 2's right now. You can work the m/s^2 yourself if you like.

How about a wheelie bar or something? Would that help?

If you did not care how it pedaled, you could have the seat set real low and much more forward. More cafe style with a much longer WB than most bikes. Sound like it pulls close to a G at a bit over 2 seconds to 88ft/second.

mnplus, where are your acceleration numbers?
