Doing an Ebike Conversion

[Vaf513]

Absolutely! I don't get bashed here for not spending 5k on an ebike!

Excellent!!

I've been very happy with my conversion so far. I went with a Bafang BBS02, a 52V 8ah battery and an 860C controller. The battery fits in the pannier with room to spare for other junk. I started with a very solid, well-built bike in good condition and I think that really helped. The only issue has been that gears 1-3 are now a bit squirrelly because the motor pushed the chainring slightly out of line, but I knew that could happen. I'll probably order a Lekkie chainring to address the issue.

I don't think I'd chance taking a motor off a pre-made E-bike and putting it on a different frame. You never know how a proprietary motor and other parts will fit on a different bike. I think I'd stick with kits that are made for that purpose. I probably could have bought a cheap pre-made E-bike for what this kit cost me with bike tools and accessories, but I'm not sure it would have been as good. This bike is smooth and powerful. Hills have ceased to exist. No more hill aversion. I'm a happy camper. Besides, I learned a lot about how a bike is put together through this process.

Kudos to the Electrify Bike Company for all their support. They're great people to deal with and it's nice to have somebody to call if you get stuck with a conversion. There's also a wealth of information on their website.

Thanks for the reply and link. I'll check out EBC. I think I finally got through to Rattan and they say they'll be sending me a new battery and display. I think some of it was a language barrier issue, both me not understanding Chinese and them not recognizing my curse words lol

Thanks for the welcome and for the input.

I don't expect to do super long rides. I imagine 10-12 miles with a single hill will be about my limit.
Still think I'll need more than 15 AH? At this point it's a WAG for me.

15 Ah should be plenty, I do a 16 mile loop with a lot of Hills and the display still shows full after this ride-but, it depends on how much you put in and how fast you try to go( 500 watt motor) the fattire bike with 750 watt and 12.5 Ah battery will drop to 2 bars at the end of this loop. Speed kills range and level of assist makes a big difference.

I decided to go with a 750 watt motor and a 52V 50 amp 8ah battery. So far it’s working out fine for me. And it saved me $100. I doubt I’ll ever ride more than 10 miles in a single day and I always pedal. Speed isn’t my thing, so I can milk some pretty good mileage out of a battery
