You can still use the 3spd, and will have to run mech brakes with either the 2sp or 3sp. The shifting mechanism uses a one way bearing, so motor brakes will not do anything. You may be able to run the savvy at a higher top speed, as the addl gear the 3 spd offers will help. Basically the lower gearing in 1st helps the motor draw less current (amps) as it lessens the load.

See the above answer... A single speed will place more load than a 2 or speed, assuming that they are all geared for the same top speed. Just imagine trying to get a manual trans car moving in 4th gear, as opposed to 1st...

Start with a smaller pinion and do some testing. Outside air conditions will have some affect on temps too, a hot sunny day, 90f and up, will result in much higher temps than a cool autum evening...
