    Chinese Retro Scooter - Running at 72v versus 60v

    Just managed to pick up this Quazzar e-divine retro scooter for cheap without battery pack. I believe it was manufactured by Ecobit back in 2015 and looks identical to any number of retro Vespa inspired scooter that have been around a number of years. It originally ran off dual 60v 20ah...

    Kelly Android App - Speed value

    I’m in the process of adjusting the settings for a KLS7275H controller using the Kelly Android app over Bluetooth. I see from the manual that the max speed is set to 4000 rpm and sure enough the motor (QS 17” 4000W) is maxing our at this figure when I look at the monitor section of the app...

    Yamasaki YM50-RE Build

    I’ve been playing about with electric bike conversions for a couple of years now, and progressed along the way, like I’m sure many on here, from standard pedal bike conversion, Enduro frame build to finally a full motorbike conversion. My goal wasn’t to create some superbike EV equivalent...

    Valence Power u-Charge P30-36C

    Hi I’m planning the build of an electric conversion of an Aprilia RS50 moped using a QS Motor 17” hub motor. I’ve been offered a couple of these 36v 30AH Lifepo4 packs, which I would be running in series to give me 72v 30AH. I need to be able to run at 60A continuous for periods of...

    QSMotor 4000W V3 17” Hub Motor Aprilia RS50 Conversion

    Hi I’ve been toying with the idea of converting an Aprilia RS50 for years and have finally sourced the donor bike. It’s in really good condition but I’m happy to have a go at converting to electric and then putting it back to gas later if it doesn’t turn out as expected. I know I need to cut...
