I'm re-furbing a bike as a commuter for my daughter. It has an old, but capable, Panda (remember them?) front hub kit on it. It has no battery at the mo, so I need a rear rack battery to fit a 700c wheel size. It's a small 250w hub, basic led display. I think the controller is max 17A...

The wife's Big Bear has developed an intermittant, but increasing, loud 'clack'. Forks and top bearing seem fine and, when riding alongside, the sound appears to be coming from the motor. Assuming that it's bearings, I've got this far: Removing the three central screws doesn't seem to get me...

Gave myself a day off today and planned a long ride through some lovely valleys and a pub lunch before riding home. About 5 miles in, I stopped for a drink half way up a long climb, then noticed the LH hub nut was missing.:oops::eek: Fortunately the torque bracket was still firmly in place. How...

I have two batteries and chargers. Both chargers read 41.7v at output and charge my batteries to 41.6-41.65v I'm not sure if this is balancing the cells, so I thought I would try and turn up the o/p voltage to 42v. I opened the YZPower charger but couldn't see a pot (photo). Is this a preset...

Just had the wife's 5 year old Big Bear battery re-celled by the ever efficient Jimmy. The old one was getting saggy on the Welsh hills leading to increasing range anxiety, though still working well. Jimmy has turned what was a 14Ah into a 19Ah using Samsung 21700 - 50g's. On charge at the...

RANT ALERT! A year ago we bought a low mileage, two previous owners vivaro combi. It has a wheel chair ramp fitted so is ideal for putting our bikes in for away rides.:) It's a 2012 and only had 29,600 miles on it - so a bargin as the dealer had taken it in part ex and couldn't shift it. The...

I have a YZpower 2A charger, it's a small one with a fan in it. I bought it as a replacement for a blown Sans one Jimmy supplied with a soft pack battery he built for me. About half way through a charge this one starts to, intermittantly, go green. If I even touch the output lead (not even...

OK, so I think lock down madness is truely kicking in now. I've been in touch with Kinetics about one of these: https://www.kinetics-online.co.uk/recumbents/hpvelotechnik/streetmachine/ I know, a bit rad - right? It's long term planning and I'm hoping it would extend my cycling life with...

I have Tektro Lyra caliper on the rear. I'm getting through brake pads at a right rate of knots. To be expected as there's loads of hills here and I'm using organic for grip. However a pair of Clarks have just lasted me about 300 miles. I don't mind changing them, after all it's one of the...

Judging by the daylight I can see between chain and sprocket and the 'chattering' noise in most gears, then I think it's time for a sprocket/chain change. The bike has done around 6000 miles in hilly west Wales and has had one new chain. The bike originally had 8x3 gearing but I removed the...

Once again my rear brake has faded away to nothing, leaving me coming down a steep slimey run of tarmac (with full panniers of shopping) relying on front brake only - at risk of it breaking away. Half way down it too wore to metal leaving me in a right pickle. So, replaced front pads - no...

I've long suspected that my Ezee hub (now nearly 5 years old) is speed control rather than power. The no load speed on max assist registers as 19mph. I suspect that this is magnetic saturation point as the motor never actually cuts out. If i rotate the pedals going downhill at, say 30mph, I...

I have one of these: https://www.banggood.com/3x-T6-LED-Headlight-Front-Bike-Bicycle-HeadLamp-Head-Light-p-1001961.html?rmmds=search&ID=224&cur_warehouse=CN It's very good at lighting the otherwise unlit roads I ride. It's extremely bright and has oncoming drivers dipping their lights before...

I have one of those little 4 cell waterproof packs, the one with a usb socket and jack type output/charger socket. Cells are duff and no longer holding charge, so need 4 new ones. Just went on to Nkon and got overwhelmed. Which cells? I use it to power a very bright 3 led light and...

Looks like the block/bullet phase connector for my motor is causing heat and possibly noise problems. It sits in this box on the fork, along with the hall connector. This is what it looks like now:oops: I need to replace it with either something that will fit in the box, or something...

Todays ride was eventful. I got something stuck in my front brake caliper going down a steep rutted lane - hairy - had to rely mostly on the back brakeo_O. New pads should sort it. The other issue was that my controller went into limp mode because of overheating. It has done this a couple of...

I've just fitted LCD5 + S06S controller with 20" Q100h. I need to find and set the wheel size so that speed etc. is correct. I have printed out both LCD5 and LCD3 instructions - but it's driving me NUTS. I turn on, wait the 5 seconds, then press up + down together. The top and bottom lines of...

So, I've just received my re-celled battery back from Insat. (8 days from pick up to delivery - wonderful). Given it it's first full charge and thought this would be an opprtunity to check my dvm. This battery, and an older soft shell one, is Boston Power cells. I use a dvm to check battery...

My neighbour has two 20" folders that he wants to convert. Not seen the bikes yet but he tells me they are 7 gears with caliper brakes and rear rack. First port of call was Woosh, but there site doesn't detail any 20" wheels. I realise the fold is going to be a big decider here. Looked at...

We're going to Derbyshire soon to stay in a glamping pod next to the Tissington trail. The wife's got a Huwei android tablet and we'd like to use it's GPS to navigate around the area/see where we are. There's no 'phone connection on it and we'll be away from WiFi. So can I get maps, or an App...
