28 inch 48 volt 1000 watt rear GM Motor

[GreenLantern]

Just completed a conversion of a Raleigh Hybrid to a 48 volt 1000 watt rear hub motor. It was a bit of a challenge for a newbie but the GM Q and A forum was very helpful. I have been riding the bike for a month and I love it. I am a heavy rider and this motor has no problem moving me along. I like the cruise control as I can set it at a pace where I can peddle. I live in the country and the neighbors think that I am in great shape because I move so fast LOL.
Hall sensors either became disconnected or are not working but the motor will function without it. I may look at the hall sensors when winter comes but I am not overly concerned.
In doing my build I decided to put the controller in a frame bag and that is working out.
I like the fact that GM has a Canadian dealer and that he (Gary Salo) answered all my emails promptly.

Bagging the controller may work for you up north, but here near Mexico I'd fry it doing that. You should consider running it with the bag unzipped at least, when it's not wet.

What's the top end with them big 28ers?

Good point about the controller Dogman, so far our Spring weather hasn't been that hot but our summers can get hot and humid.

Wineboyrider I haven't installed a speedometer or used a gps but I think flat out I am getting 30 mph maybe a bit more. I know I can go much faster than my Schwinn IZIP which tops out at about 22mph. When I get an exact reading I will post again.

I installed a bike computer. The bike cruises between 35 and 45 kph. In 18th gear(which allows some peddle power)and at full throttle I got as high as 51kph. That's just over 30mph. Lots of fun on my country roads.

How'd you get cruise control? I'd be interested in something like that.. seems futile to keep holding the thumb throttle

 

[GreenLantern]

The GM has a cruise function but not true cruise control. You press a button to hold the throttle setting. It does not hold the speed though so if you come up to a hill you will either slow down or have to pedal to maintain speed. You can use the button or apply brakes to cancel the cruise/throttle control.

Yeah those big wheels give you a little more speed at wot than 26". 8) 8) 8)

I just added a 52 tooth chain wheel to replace my 44 tooth chain wheel. I hope to create a little more pedal speed at full throttle. If i could also find an 11 tooth freewheel(not cassette) that would be great. I will post after my test flights LOL.
