    So it isn't a one to one ratio with the crank, easy to detect in software.

    Oxygen E mate MTB13AH

    The Yamaha battery doesn't appear to be "switched on" until you power the bike up. Yes there is a voltage reading at the terminals but it is a couple of volts lower than the actual battery voltage. If I fit the standard battery and then measure the voltage on the connector for my extender it...

    Chainrings - is this correct?

    You don't need to mount a spider, the Yamaha motor has a spider capable of taking 2 chainrings as standard although iirc the chainring is on the inside of the spider and the chainguard on the outside. When I changed mine back in the mists of time I had to use different bolts but I was making it...

    Chainrings - is this correct?

    Well mine must wonder what the hell is going on as I never do more than 7mph! It didn't die when I increased my chainring size from 38 single to 44 outer and 32 inner. Bosch may use such algorithms but Yamaha certainly don't.

    Chainrings - is this correct?

    What a load of rubbish, it has no idea what gear you are in, the motor only delivers power proportional to your input. It doesn't know what gradient you are on or how heavy you are both of which have a far greater impact on what the motor is doing. If it is possible to get a narrow/wide single...

    2018 Yamaha Electric Bike Updates at Interbike

    The 500Wh battery is a straight replacement for the 400wh, I used to hire one before I got my extender.

    eMTB owners photo and ride thread.

    Most of the Alps has had some snow this week, Kleine Scheidegg was the only place my jaw has ever hit the ground in awe. I was working in Switzerland and had weekends free, thought I'd go skiing at Wengen for the day. Drove to Lauterbrunnen and caught the train, when I got our and walked out of...

    Out for a ride this morning, couldn't quite get to where I wanted to go. Had to turn round at 1700m. Still pleasant towards the valley, the cows come down off the mountains tomorrow ready for the winter.

    Do You Insure Your Bike

    Not insured, my usual mantra is if you can afford the risk then why throw money away. I do however have personal liability insurance via my home insurance, I can't afford the consequences of killing someone.

    Cost me €5 per day to hire a 500wh Yamaha battery before I fitted my extender.

    Switched to Haibike SduroTrekking

    Before I got my extender I used to borrow a 500wh battery from a local hire place for €5 a day;). They wanted to charge me less but I just gave them 5, when I first asked I was expecting more than that.

    Chain jumping/slipping under load

    What's going on with the diagonal marks on the chain? Certainly looks like its not indexed properly to me (or mech hanger is bent ). Speed sensor magnet could do with truing up too.
