    front hub, mid drive or rearhub motor choice

    I recently converted my mountain bike using a front wheel hub from Topbike (China). I was a bit sceptical about front wheel drive as well, but I already had an Alfine internal gear hub at the rear and didn't want to lose that. Front wheel drive works very well for me and I've not experienced any...

    Lightweight rear hub kit

    Hi Kyle, glad you found it useful. 1. I didn't have any concerns about the motor overheating – just didn't need any more power. My wife likes to pedal and just uses the motor in low assist modes: level 2 mostly and occasionally level 3. 2. A comfortable 20 miles range with the 7 Ah battery at...

    Lightweight rear hub kit

    Just a little follow-up. Discovered a feature that's not mentioned in the manual for the KT LCD4 display. My wife came home after dark last night complaining that her hub motor was no longer working. I checked the bike in the garage and everything worked perfectly, so I took it outside for a...

    Lightweight rear hub kit

    So my parts arrived from Topbikekit two weeks after placing the order, which is better than I expected considering the Covid situation in Hong Kong. I built the wheel into a 27.5 Alex rim using Sapim Leader 14g spokes from Ryan. This was a first for me, but jobs like this are so much easier...

    Lightweight rear hub kit

    Thank you Jodel, that's good to know. I was wondering about adding some spoke washers. I guess I'll have to wait until my hub and rim arrive so I can double-check hole sizes and effective rim diameter before ordering spokes. I'm itching to get started now.

    Lightweight rear hub kit

    Spent a couple of hours this afternoon reading about spokes and nipples. Too much choice... Checked the existing front wheel and it has 14g/15g double-butted spokes. I'm thinking that plain 14g should be fine for the rear wheel I'm going to build. Is there any advantage in using double-butted...

    Lightweight rear hub kit

    I checked the calculator for both lacing patterns. Single cross gives a nipple angle of 5 degrees, and double cross gives 9 degrees, so I think I'll stick with single.

    Lightweight rear hub kit

    Thanks for the video suggestions guys. Watched them all. The Grin Tech video is especially useful as it recommends no more than a single-cross lacing pattern because of the larger diameter of hub motors. I'm looking forward to having a go at this.

    Lightweight rear hub kit

    Just ordered an AKM100CST hub with T-06S controller, PAS and KT LCD4 from Top Bike Kit – thanks for the guidance Neal. It took some time working out which sensor would fit the bike, but eventually went with the BZ-10C. Would have liked a higher magnet count, but I can always upgrade later. I...

    Lightweight rear hub kit

    Neal: I just noticed your guide to selecting components from Topbikekit. Much appreciated! I'll take a closer look.

    Lightweight rear hub kit

    @Hummer: It sounds like we're chasing similar solutions, though I'm limited to rear wheel motors as my wife's bike has carbon forks. I'm also very tempted by the Cytronex kit for my own bike, but as mentioned it's on the pricey side. I got a reply from Woosh about the 85SX kit. Unfortunately the...

    Lightweight rear hub kit

    Thanks Neal, that's a bit heavier than I want.

    Lightweight rear hub kit

    Thanks, any idea which motor that is and how much it weighs?

    Lightweight rear hub kit

    Thanks, I appreciate the suggestion Neal. I'm trying to avoid putting more weight on the front of the bike because my wife has arthritis in her hands. She had an old Giant ebike with a front hub and found the front end too heavy and the steering rather sluggish. It was fine in a straight line...

    Lightweight rear hub kit

    Thanks for the replies! If there aren't any suitable kits with a 27.5/650b rim I guess I could use a 26" rim and put a larger tyre on it. I think a 700c would be a tight fit. I'd really prefer a complete kit, or at least a hub/controller/pedal sensor package that is already configured to...

    Lightweight rear hub kit

    Hi, first post here, and I'm hoping to get some advice from you knowledgeable folk. I converted a couple of bikes for myself a few years back from individual components, but now I'm Iooking for a rear hub kit for my wife's new bike (an Islabike Joni). The kit has to be as light as possible as my...
