Mind you after 5,291 miles it still runs and I could either fix the clutch which I epoxied at 3,051 miles when a hall sensor failed or replace the clutch entirely with a spare I have but since I bought a front geared motor from E-BikeKit a little while ago I took this chance to try it out (see my first impressions here; viewtopic.php?f=4&t=18349#p270317 ). I was planning to lace the new motor into a new rim with new spokes in a 2X pattern however I never got around to ordering the items figuring IÃ¢â‚¬â„¢d wait until the Bafang gave out. I could still do that but I wanted to get back on the road as quickly as possible therefore I re-used the existing Sun Rhyno Lite rim and DT Swiss 247mm spokes. The E-BikeKit Geared motor is about 11mm smaller in diameter than the motor it replaces but going from 12mm to 16mm nipples addressed that issue. The 1X pattern introduces more spoke twist than IÃ¢â‚¬â„¢d like but what ya gonna do. The holes in the flanges are also rather large for 14G spoke heads but then so were the BafangÃ¢â‚¬â„¢s.
I got the new motor laced up and ready to go by late this afternoon. I only used the motor from the kit choosing to stick with a 21A Ecitypower controller and my trigger throttle. On the stand the no-load speed was 28.4 mph at 51.0V or just a hair faster than the 36V BafangÃ¢â‚¬â„¢s 27.5 mph at the same 51.0V (w/700C x 50mm tire). ItÃ¢â‚¬â„¢s a slow wind to be sure but IÃ¢â‚¬â„¢m not complaining.
Out on the road the E-BikeKit geared motor (it needs a cool name) felt stronger than the Bafang and was a bit faster at a top speed of about 22.5mph. On this first ride over a familiar 18.2 mile course thereÃ¢â‚¬â„¢s only one significant hill but the motor did pull better up that grade with less protest. By the end of the ride I was quite satisfied with the performance. I finished the ride at an average speed of exactly 20.0 mph, which is quick for me, and consumed 11.63 Wh/mile in the process, which is low for that speed.
Overall IÃ¢â‚¬â„¢m happy with the motor especially at the price I paid. I do believe however the kit will be better when Jason has the wheels built in-house and combines it with the tried and true 22A Infineon controller, though then it will be sold at full price.

I fried my stock version today and was in contact with Lyen to get a new one.
