Re: My Cromotor E-Bike Build -> more like a moped

My build still looks like a bicycle with a bomb wired to it. I haven't gotten to the refinement in looks part yet. Wanted to road test it to see if all the tech works first. It's over 100 lbs but the weight is well distributed. Braking not an issue because of regen braking. It's a 28s build but wan...

Re: My Cromotor E-Bike Build -> more like a moped

Good job. I made aluminum panniers positioned where yours are on my cromotor build. Hopefully I will be able to add polishing touches to mine soon also. PS What a learning experience. Don't you agree? PPS I was shocked at the build weight of a cromotor bike. It's almost like a really light motorcyc...

Re: My Cromotor E-Bike Build -> more like a moped

good news: now my variable E-brake with brake light switch works how it should. The issue i had was a broken GND wire from display to e-brake / throttle connector. The wire was already broken when i got the controller. The curious thing was my 0-5k thumb throttle worked WITHOUT gnd connected to the ...

Humm those are way to bulky, and I need 8.4 volt, 9V tops. The light drains around 2A. The light came with a charger 8.5V 2A maybe I can connect it directly to the light? so your lite does have a battery inside? do you have link?

Re: New Bafang Crank-drives

Unfortunately not without having access to the software. you will get 35kph to 40kph on PAS with an 11 tooth on flat road. 450W is all you get when on PAS. I am sure they have set it up this way so you don't destroy your gear system. ok that will be the cause. it will last longer and also doesn't g...

Mine only worked one time and than the resistor blow up. anyway i think i will stay with them, because i hav...

@ Kepler thx for your experience report. Is there a way to set up the unit to give full power out of the controller also with PAS assistent and not only throttle?

Re: Big spark when connecting battery to bike

Got the ones from HK in today. Across resistor only measured 5 ohm on mu cheap DVM, but that's about the same as I got with my 40 yr old rat shack analog meter too. I'll try one when I get a chance, which may be a while as I've got other things to do, but I'm not too optimistic since I use 150 ohm ...

nice and clean build. I like these Bafang crank drives.
is this the 750W unit or a lower powered one?
what battery are you using?

Re: what is the 3 speed switch

You can program 3 different controller speed limits and switch through them. for example 33%, 66% and 100%. If you push the throttle, the controller will not spin faster than this setting. There also is the option to set to max 120%. This will cause in much more speed downhill and only a bit more sp...
