Converting front Hub motor to a rear hub motor?

[jerbyrd88]

I have a wuxing 36v 500w Ebike kit I picked up for $100 I couldn't resist. I used to have a 48v 1000w rear hub motor with a 1500w 35amp. controller and they was on a Giant Revel 2 and that bike did about 35 mph consistently. I'm wondering if I can convert a front hub motor to a rear hub motor by adding a sprocket somehow? Or is there more to it than that? Also how hard is it to bump the 36v motor up to 48v or even 60v? Or is it just not worth it and buy the larger motors? Any help would be greatly appreciated. Thanks in advance

You will need to get (or make) a threaded side cover for the motor, and add axle spacing to match the wider rear end of your bike. There may not be enough axle length to do this. If you make a different axle, you can include the appropriate spacing.

For most people, converting a front motor to a functioning rear version isn't feasible.

What's your aversion to using a front hub motor? For a low powered one like that, front mounting has a number of advantages.

If it's a geared hubmotor (which is likely) then you might consider keeping it on the front.

You could add a second motor to the rear, such as a common 1000W direct drive hubmotor, and doing that would also provide the option of regen braking your make your rim brakes last longer.

Can a front hubmotor be converted to work in the rear. I say yes, but...all of the several methods I could use would be so expensive and time-consuming that it would not be worth it.

If you want to keep just one motor in the rear, buy the kit you really want. Then buy a $20 thrift store bike to put the front motor on. That front-motor ebike can be for friends to ride, or you can sell it.
