Thank you for all that helped out on my first build. The Sphere provided a plethora of info to get my ass on the road!!......on to the next

New to Forum and trying to keep up the learning curve.

A Giant Boulder aluminum frame


It's a Goldden Motor front 500w 36v kit that came with the 36v 12Ah SLA pack. I've since gone to 48V 12Ah SLA but 40lbs of weight on the rear rack wasn't making me nor my panniers happy. Made a picture to justify to me the benefits of switching to lithium.


I've collected a couple laptop batteries and made a pack with em. Soldered a bunch of Deans Pro tabs to the 2 packs on the right and the rainbow colored one I made with cells of similar voltage and soldered 12ga wire across 4 pairs to give me 20Ah using pairs of 2500mAh batteries. So the picture shows 3 packs of 18V 20Ah 5s4P.

My cheap hobbyking charger peaks them at 20.5v each so it's a 61.5v pack at 20Ah(more like ~10ish realistically)

This is how I use it now. With the Li-Ion pack I can do 20MPH(32kph) without trying and I've topped it out at 34MPH(54.7kph) downhill(phone gps)


Hope I didn't leave anything out. Hope you enjoy.

[friedwires]

nice work! where did you get that threadless stem extension? i've been looking for a way to raise my bars about 2"

[FastDemise]

I got the bike off Craigslist with the extender but I believe I saw them at my local REI store. Hope that helps.

Before....


After.....


Seeing I didn't know much about bikes I decided to build one part by part so when it came to servicing i would know what to do.

There 18s2p lipo stuffed into the battery box, and the motor is the hs3540 although i really wish i went the HT instead.

Since the 'after' i have made much larger cooling holes in the motor, and a vent/window in the battery box.
Just sorting photos to make a build thread so keep your eye out

Another kona, lipo 74v 5a(so far) and crystalyte hs sensored. The box is made of a sheet of lexan which I bought at home depot. I folded it with a heat gun than painted it.

[hillzofvalp]

like it a lot... how much was that bike alone?

[anothercanadian]

I bought it used for 500$. I think it was sold for more than 2000$ when it was new.Surprisingly stable at high speed with a double suspension

Nice. Is the controller inside that box too? It would be great if you can start a new thread showing the technique for folding lexan with a heat gun. I have no idea how that is done.

[hillzofvalp]

you have to set up good right angle jigs and work fast with gloves to protect from hot plastic. If you over heatt it or let gravity pull it you won't get an even surface. worth experimenting over but any long lengths (15"+) get hard to bend cleanly because keeping the heat distributed is difficult...
