Top end before the smaller spocket was 28 mph.
I would love to have a Bakcou or Quietkat but didn't want to spend that much.
I recently bought some wheels to make a pull behind game cart.
#1 They claim 28 miles with the 48 volt battery back. I've gone 10 miles and it still showed 3/4 full.
#2 The motor has a tube that slides into the hub where you pedals ride. Google Bafang 750 watt conversion and look at the video.
#3 The tires are 26 x 47/52. Just under 2" wide.
#4 the standard kit comes with a 48 pt sprocket. Upgrading with Bafang is pricey so I bought one from Walmart that is 40 pt. I'm still mostly driving around town so I haven't installed the smaller sprocket yet.
I didn't purchase the recommended $20 spanner for the hub nuts. I managed with a punch. I did have to purchase a $18 pedal puller. I couldn't get the pedals off without it. At least not in one peice.
Or is that just to create the electricity to charge the bike so then there are no emissions?

My Salsa Timberjack has a bottom bracket that says 73 mm BSA.
Unfortunately they are out of stock on the sensors for hydraulic disc brakes. Curious if it can still be used with out the sensors.
The motor has started to develop a little bit of a clicking sound so I’m not sure how much longer it’s going to last. It’s super powerful mostly I ride it on level two (of 10) The only time I kick it up to five or six is when I’m going up something super steep.
I would have more mileage on it but this time of year around here they have those goat heads that kill your tires.
The downside of these kits is it makes your bike super heavy…too heavy in fact.

I can't really say how long it took to install. I worked for a while and then hit a snag. Had to drive down to the bike shop and buy the pedal puller. Also, the battery pack didn't want to fit where I wanted it to go so I messed with that quite a bit. If you have no issues and have the right tools probably not more than a couple of hours. After doing one, I could probably do another a lot quicker.
Mine is the sandard size bottom bracket. It fit perfectly. I don't know how well it would work without the brake sensors. They put the motor in neutral when you apply the brakes. I expect that would be an issue.
That's probably why they are all gas powered.
