Nope. But I do have a 36v controller I might use for a different project.

You don't happen to know of cheap 36V controllers that can handle about 400Amps do you?

[BL_RV0]

What's your idea of cheap?

[J57ltr]

A dolla. It's got to handle a 3 HP series wound motor (golfcart). Less than $100.

No I don't. Sorry Jeff.

Got my new sprocket and chain in!

It's coming along nicley, are you working on the frewheel to your front gear cluster now or did you already finish that part? This was always one of the sticking points I had for adding an electric/pedal powered bike. You said the freewheel was gritty were you able to clean it?

I have always wanted to build one. When I was about 15 I saw a pair of bikes that had a engine that was strapped over the front wheel and when you wanted to run the engine you moved a lever that moved the assembly onto the tire and a friction drive roller was put in contact with the tire starting the engine, apparently they sold a few in the late 70's.

Since my dad moved I no longer have access to the tools needed to remove the freewheel. I shipped the unit up to him and he'll take it off for me. I'm not sure when he'll get around to it, but hopefully soon.

great build , i am just lurking here since i am thinking of getting a 3 wheel adult tricycle for my dad , and this is what i was thinking of doing with it

not to hi-jack but anyone who has any thoughts are welcome to pm me , but i am thinking of a tricycle for an adult with a similar setup (or a hub in the front wheel) so to it can still be used normal when possible , thanks

Thanks eric.
Tricycle idea sounds pretty good, but why not something like a recumbent?

its for my dad to get back into the woods , he doesnt get around to well anymore, and it would be very stable for him... , where we hunt there are some great walking/hiking trails that are good enough to bike, he cant walk the 2 or so miles in and out everyday , so i have been looking into a 3 spd. 3 wheel bike for him and he is very interested , and the electric front hub would be his hill/slight grade assist

i guess i will just have to see what he wants to spend....i found a single speed 3 wheeler at walmart for $250 , but a 3 spd. would be better imo..and the bike shop said they can change the main gear to help with the gearing advantage but the 3 spd. was $480 (better bike of coarse) and the electric conversion they sell/install would get this bike to about $1500 total with the bike....

i know if i did it with a single speed and did the conversion myself i can do it much cheaper

i am just in the research stage now

BL_RVO,

Do you have any pics of the freewheel assembly?

Jeff

[BL_RV0]

I don't. I shipped it to my dad for removal before I snapped some...
