I ventured out to piece together a proper eBike conversion kit.

Here it is...

Pieced together from different eBay venders.

Only thing I want to add is a proper mount for the controller box. Right now it's strapped in with a universal bottle cage mount and it seems a bit flimsy.

Pretty cool.
I am curious about the twin rollers on the fender.
Do they work well or does the fender flex too much when turning and such?

They work great!!!

Makes my Brommie less Tipsy when folded.

What's the brand/manufacturer of the hub?

That's amazing! How much weight does the conversion kit add to the bike? How fast will it go in eBike mode, for how much time, and how long to charge? Does it plug into a standard wall outlet?

And how about rain - it looks to me like rain would be a disaster for that setup.

Pretty awesome though. You should post some riding pics or videos.

The Schwartz is strong , on that one..

I would love to hear your review of the Add-e. Distance, support, battery life, etc. Seems to be very little information on the web from people that actually use this tech.
It seems the advantage of the Add-e is weight. The standard eBike conversion kits seem to add quite a bit of weight and are not removable like the Add-e. Anyway I would appreciate your comments.

FWIW, Brompton is going the e-bike route too At least that is what this article says ...

Unbranded on eBay but I think it's this...

That one is 100mm,the Brompton has a narrow hub.

I have ways to make it work...

Did you spread the fork, or take some spacers out?

Looks like a fantastic job, beautifully done. Just noticed the very neat IEC socket in the front bag. What's in the bag?

I slowly widened the fork.

36v 10Ah LifePo4 Battery.

Ah I thought the battery was on the top tube. Now I realise that's the controller that you mentioned before. I would have put the controller in the bag as well. But... the controller is huge, is that box full of stuff, or can't it be opened?

It would be fantastic if you coul list the vendors. I have been very actively considering going this route but lack time. Your help would be much appreciated.

That black box on the top tube holds the controller and all the cables. Most of the space inside the box is taken up by excess cables.

In previous builds I had the controller and battery inside the bag. But the disadvantages of that is heat and portability.

I'll put together a parts list when I can.

Retrofit procedures include spreading the fork, from 74 to 100

Here's a cool Motor/Battery Simulator to while away the hours.. lots of variables to plug in including weights, wind, incline, etc.. this will get you close as to what will meet your needs..


Justin also has Brompton Kits .. check out his videos.. Justin is definitely experienced ..

I have one of his low powered front hub kits with torque sensing bb going into a Litespeed Ti road bike as we speak..

As a strong rider, you will flat love a well executed e-assist bike.. especially as a commuter.. higher speeds with less time spent on the road, and less sweat .. excellent cardio if you keep your cadence up too...
