    YOSE or Whoosh or Boost, or Something Else, for Conversion But Legal?

    I wasn't aware of side release - every day's a school day! I have looked at side release now, but I haven't (yet) found a 36V one of close to 20Ah, thus not yet matching the "up release" DP2170 version that Andy at Woosh suggested. The side release all seem to be about 10Ah or 13Ah, and the...

    YOSE or Whoosh or Boost, or Something Else, for Conversion But Legal?

    There's been a lot to think about, with all the advice here and prompt responses from Andy at Woosh. I did a cardboard template of the Woosh higher capacity DP2170 36V 20Ah battery that Andy suggested might be an option, but it looks very tight, due to the combination of it being slightly...

    Thanks for the quick responses. I'm not going to be doing any serious MTB stuff, I'm too old and injuries take too long to fix, so I'm a pretty cautious rider. Im doing bridleways and byways, bike parks, that sort of thing, not crazy rock-strewn climbs up real mountains. My efforts on CAD...

    YOSE or Whoosh or Boost, or Something Else, for Conversion But Legal?

    Hi all, my first post here. I currently have an old btwin MTB that I bought secondhand over 10 years ago, and also a rather tired 20 year old Trek (a cheap recent impulse purchase) and I'm getting back into some intermediate level mostly off-road stuff after not doing much riding for a few...
