    Yes, I had wondered about the idler. Just went to look and there's certainly enough room and mounting brackets , however the idler can spin independant of the chain despite having teeth (may need to look at that) but it's a possible.

    Rear lights - recommendations?

    I bought one of these for the bent. https://www.amazon.co.uk/AWE%C2%AE-AWEFlashTM-Bicycle-Light-Lumens/dp/B00P2PPZW6 Flash is one button press and is really bright, also no faffing with chargers. It's a plastic jubilee style band that I think would go small enough to fit your rack. At that...

    Love to buy from you Tony(save a lot of faffing) but, at this point, I don't need a battery and, as far as I know, you only sell complete with batteries. Also I can't see the 128 on your site. Am I missing something?

    Love to fit to the small ring, done it on my carrera. However on this one there's a rather substantial steel ring guard, it's all a bit tight on that side. Only a couple of mil between small ring and ring guard stays. So I think I'm going to need a pas with the detector that would normally fit...

    It's a square taper BB. I've had the same issue on two bikes now. The pas disc doesn't grip the shaft tightly and can develop a wobble so that the distance to the sensor is variable, and also develops rotational slip. In both cases the crank was removed so the disc could be slipped off...

    There are some tough hills. I take the 50% approach, that is I try to keep the minimum climbing speed equal to or greater than 50% of the modal speed. So around 8mph for a 15mph motor. My Ezee has never felt even vaguely warm, the controller however is a different matter. Hence the 9 fets.

    Yes, did wonder about the 12 magnets, seem to recall people having issues. Not too bothered about changing levels, though this may be because my Ezee is speed control rather than current level.

    My name is ..... And I'm new here.....

    Maybe some of the non slip strips that are sold for decking. These are hard resin strips with a coarse grit embedded. They could be screwed down?

    I've put together a list of gear. This assumes that I'll start with existing 36v batteries and migrate to 48v when I've learned the handling of the 'bent'. Therefore I've specced a 36v motor (which is quoted at 201rpm) which should take it to around 280rpm at 48v, when I'm ready for higher...

    That can't be right, can it? They're showing torque washers with the nut assembly. Aren't the diagonal lines on the shaft indicative of a flat? I would think that a motor without flats is a spin out waiting to happen.

    That's the info I need, thanks. I seemed to remember you praising the 128 in the past. So we are looking at this one then: https://www.topbikekit.com/akm128h-36v48v-800w-rear-driving-hub-motor-for-ebike-p-889.html?zenid=hu5kfe8pjohgvnvvi7c8o49nt6 They are recommending the T12H controller which...

    Preferring to stay at 36v I'm looking at this https://www.topbikekit.com/akm100h-36v350w-ebike-rear-driving-hub-motor-p-679.html?zenid=uneijs4gkrjafo7kuukugufi07 No torque figures are quoted so not sure how it compares.

    I've only gorn and dunnit !

    Took the bike out to Pembrey Park today. Midweek so hardly anyone around and plenty of empty carparks to hoon around in. I learned that I'm not yet safe to be on open roads, some of the wobbles were quite pronounced. Also the bars were slighty off centre meaning my left leg was rubbing on my...

    Many moons ago I used to work for BT. I saw what 50v D.C. was capable of, although with potential of extremely high current. It makes me a bit wary of 48v. Is it really OK - out in the wet (does happen even though I try to avoid it)?

    It's west Wales that I've been cycling for years on a front hub with only a body weight shift to the front, on steep bits, and no standing. Current kit is based on an Ezee. So it's this high torque that I would look to replicate. If I could find an unmarked Bafang BPM, that'd be nice. Here's...

    Good shout Neil, thanks. Hard to tell from the photos but it looks like the motors are unlabelled. Is that right? 'Cos if so the 100H looks apealing.

    I'm struggling here. I want to get rid of the Dillinger kit on this bike but am struggling to find supplies. So, here's what I'm looking for: Rear wheel hub, cassette or free wheel, don't mind, currently has a 7 speed fitted. 26" wheel. 9 or 12 Fet controller (there's a lot of hills around...

    Hub Motor rattling - not a lot but annoying

    You're not going to believe this, but have a look anyway. Hub motors can make a real mechanical sounding noise, even with vibration coming through the handle bars on a front hub, when their electrical connections are poor. Told you you wouldn't believe it. Have a look at ant connectors on the...

    This is turning into a saga. Got the chain links today, still waiting for the tools. Got a nice new shimano centre lock disc for the front. But, oh bugger, it's 180mm not 160 (no bad thing I suppose), so just ordered an adaptor. New pads on their way. Very bright flashing twin rear light...

    So, the Son dynamo is a through axle or bolt with a very wierd unique shaped nut which I'm not sure I trust that much. The socket the previous owner sent me has a very small stress crack in it and I can see it failing. Does anyone know what these things are called? Can I replace it with...
