    I've just seen the Haibike sduro all mountain and gone a bit dribbly. and I'm rethinking and reconsidering mid drive now.

    Cheers John/Mike, my main use of the motor is for the uphill slog bits where the front end is often so light that I have to take care not to 'wheelie' off the back of the bike. I definitely couldn't lose the granny ring. I'm pretty certain for the type of riding I do I wouldn't want to be...

    Cheers John, can I spec the kit completely including the 500w CST rear motor and s12s controller through you? That didn't appear to be an option on your site. I would certainly rather buy from a uk supplier with it's consequent back up but from everything I've read on here the 500w motor is...

    Leisure v Utility

    FWIW. currently I commute by bike most work days but it's short distance stuff (3 miles each way) but leisure is distance stuff. so on numbers of journeys it's 80% commute but distance would be 80-90% leisure.

    cheers Trex, yes, I already have one of these chargers and if I end up going the two pack route with these batteries I'd definitely go for a second charger

    I wasn't intending it to be throttle only but I do want the thumb throttle option. I was, however, envisaging that if I'm actively using the thumb throttle I'm not pedalling. battery mounting looks like the biggest hurdle to be honest. I've had this bike since new in 2000. We've been through a...

    Hi Trex, do you mean two chargers per 5s pack? I was thinking a couple of the battery alarm units that plug in to the balance connector on the packs and give an audible alarm if you get to the LVC point would be a good shout. Thanks jackhandy, it's always difficult when you're first starting...

    so spec'ing kit I'm thinking The 36v 500w CST bpm2 motor (this will let me use my existing 9 speed shimano slx cassette and retain my nice slx shifters also) The matching s12s 500w controller The compatible lcd 3 display unit all from BMSB in the US then from the uk thumb throttle. this alone...

    Being a bit of a tart I really like the look of the old girl so don't really want to add racks if at all possible. would like to keep the lines as clean as possible. I may end up longer term getting something custom built to house the batteries either side of the top tube if I can't find an...

    Cheers JackHandy, yep, this is totally a toy for dirty fun ;) I've got my normal alu framed commuter roadie and a full carbon 'sunday best' roadie also for day to day commuting and road based rides. I'm pretty much looking for a push bike based equivalent of a green laner motorbike. So...

    Thanks, I had forgotten about the 'public access' bit. lots to think about and inevitably none of the off the shelf kits appear to cover all the bases for what I think I want at this time.

    Hmmm, I've just mocked up the woosh 15ah battery sizes in cardboard and tried it under the frame. if I sit it flush with the angle of the down tube it sits too low and will get clouted every time I go over a ridge. I also don't like the look of the bike with it hanging there either so it's...

    this is all sounding promising. my bank account is already starting to tremble! what hub motor are you using? Having never used an e bike I'm tempted by the woosh complete kit with the 350w bpm motor as I've got almost everything from a single supplier in the uk. I'll have to sort out something...

    oh yes, its a hollowtech 2 bottom bracket as well if that makes a difference.

    Convert my Rockhopper help

    There are a couple of water bottle bosses on the lower edge of the down tube which would put a bottle type battery in the gap between the bottom bracket and the front wheel. I suspect though that this would probably foul the front wheel if I go with a battery large enough to give me a decent...

    Cheers Jackhandy, I've got a couple of bikes for playing on the road. This is just a toy for the dirt so the 250w road legal bit is a non issue. I more interested in finding a kit that will meet my needs.

    Hi all, I'm looking at getting a kit for my bike and could do with some help. I've got a nice year 2000 specialized rockhopper which has been fettled over the years from it's original spec. runing a triple chain ring at the front and 9 speed on the rear. I'm 11 stone, pretty fit and cycle to...
