I purchased this kit a few months ago and have been quite happy with it thus far. A few notes:
I ordered the 24 volt kit and received the 24 volt controller and charger, but
they sent me three batteries by accident. I would like to 'upgrade' the system to 36 volts or maybe even 48 volts. The brushed motor will take 36 volts for sure (according to WE) but not sure about 48 volts. Any input on third party controllers/chargers/etc is appreciated.
The hub came pre-assembled on a 26 inch rim. A couple of the spokes were broken and had to be replaced. The hub is HEAVY, and with the batteries the bike is actually quite difficult to even lift.
I needed a new fork for my bike as the existing fork did not have enough clearance. You need to measure not just the clearance at the axle but also about 3-4 inches above the axle.
I attached the rear rack to the bike seat bolts and another set of holes below the bike seat. It would probably be more stable with the second attachment point at the rear axle. The rack itself is rather cheap but functional.
Attached is all the information I have on the Wilderness Energy BD-24 kit. The scans are of everything I received with the kit. Yes, they are shipping out some pretty poor photocopies of photocopies of the manuals. Some of this in in Chinese, and any help in translation is appreciated. ***note: the forum won't allow me to attach the document as it is close to 1mb. pm me and I'll send it to you***
I was initially disappointed with the performance of this kit, but over time have come to appreciate it. I don't have a speedo on this bike so no quantitative info. I like to go a little faster than the motor will take me so I pedal most of the time, but it is a whole lot easier than it used to be, especially on the hills.
Definitely interested in putting a few more volts on the system, so again any info/comments are appreciated.
