fancy saddle and grips! :)

maybe they are concerned for you since by your own admission, you have a " barely adequate wired headlight and tail light/brake light" and so decided to follow you to keep you safe from other cars? I know, placing too much faith in humanity, but you are likely better off with someone following...

OK, i have no idea why it didn't work, so i took the tape off and plugged in the extra ebrake, put the bike up on the stand and powered it up. The bike worked fine. So to prove that it WAS the ebrake, i removed it and it still worked fine! Took it outside and it worked fine when i pedaled...

My wife's bike is complete and she's very happy with it... Mine however... the throttle works but there's no power when pedaling... I did not think i needed the electronic brake so i left that off and kept the original. is the ebrake integrated with the torque sensor? DO i need to install it...

Oh i want to scream! So i trimmed the cable holder down. Not enough. trimmed some more, still not enough. trimmed some more and because i reduced the thickness, the screw that holds it was too long and protruded on the inside of the spindle housing. Ground the screw down... Twice. The motor...

OK, it looks like i need to remove the cable holder from underneath the crank housing and trim it down and reinstall until the motor fits...

So i got the shimano tool and removed the crank spindle. Next step is install the motor... easy-peasy right? Guffaw. What none of the videos that i found so far address is the fact that the rear derailleur cable runs under the spindle housing and is directly in the way of the motor. not sure...

the motor as a single gear if that's what you mean? The bike i am working on has a 9 speed cassette. I don't think i need to shorten the chain since she has 3 speeds in the front with the smallest gear being 26 teeth. the motor comes with a 44T gear so if the derailleur worked with the smaller...

OK! Thanks for the tips!

Next question. should i install a new chain? Is there a more rugged chain for ebikes, or just leave it and buy a spare in case it ever breaks?

I ended up drilling the brake lever post out and it worked well. Looks decent. Everything i found on you tube was really kludgy, using epoxy or electrical tape.

OK... i have a question. both bikes have the read derailleur integrated with the rear brake. I need to install the new brake with the motor cutoff switch. I am thinking i just need to remove the brake lever from the original combo but it may be that the pin is pressed in with a flange on each...

The kits arrived today (TongSheng 750W motors) and i am digging right in. All the parts look pretty rugged and i am happy with that. Started on my wife's bike first. The first issue i encountered is that 30 years of moving and 4 kids messing with my stuff, my crank puller is not with my bike...

Seems the batteries i bought come with a charger so i am all set...

I think i neglected to buy a charger with my 48V 20ah batteries. can i use a 12v car battery (50A) ? Thanks! I have not received my invoice yet so i am not sure if i did or not.
