Last week, I blew the motor on my bicycle because I was commuting into wind gusts for about 1 hour and cooked the motor.

If I order an exact replacement, I would be ordering a:

450Watt 24Volts motor that is spec'd at 3000 rpm, 24 Amps.

However, I'd like to replace it with something that is less likely to cook in the future.

I've found bolt in replacements that are spec'd at:

36 Volt, 450 Watt, 3000 RPM, 16.0 Amp,

I have a few questions about this, but I'd like to start off with a simply one.

How will this affect my performance and reliability?

Thanks

Ok, I think I can safely answer one of my questions by myself....

Answer #1: running a 36Volt motor on a 24Volt battery will cause a reduction in performance because the motor will no longer be operating (or trying to operate ) at 3000 rpm.

Sounds like you've already got a handle on this, but if you haven't already, consider stepping up to a 36V system. Depending on how you ride, you may be able to see a SIGNIFICANT improvement. . .
