According to Sheldon Brown that rim will take a tyre 28c-44c https://www.sheldonbrown.com/tire-sizing.html

I stumbled across this cheapy one on Ali but I can't see anything about replacement tips but could they be easily made/copied...

Everything you need to know about wheel building is in this excellent book (well worth the cost) and he has a spoke length calculator on the website too. https://www.wheelpro.co.uk/wheelbuilding/book.php There is also sheldon Brown's great guide. https://www.sheldonbrown.com/wheelbuild.html

I made an adapter lead between the charge plug and the battery, after a few months of it being flexed I got that same problem, so I did what vfr400 says, took it to bits, resoldered it and the problem was gone.

.SOLD.

I'd not put a price for the motor wheel and controller kit so am thinking £150

I've also had a scab patch fail about a week after sticking it on which gave me the opinion they are temporary and need replacing for glued patched when I get home and can do a good clean job.

This grease gets recommended in the Q&A for being mineral based and somebody used on Bafang motor nylon gears although not done it myself yet. https://www.chainreactioncycles.com/weldtite-tf2-lithium-grease/rp-prod5959

Out on the road bike yeterday I found a bridleway signposted so came back today on the emtb and had a great couple of hours. Will be going back. This is steeper and rockier than it looks and beyond my zero offroad skillset.

It sounds like the wheel isn't in straight and the tyre is rubbing the frame causing the drag and will also cause the indexing to be out.

Ask someone to lift the back wheel of the bike off the ground while you give it a spin by hand to see if there is any resistance and look to see if it is the tyre rubbing against the frame, or the disc rubbing inside the caliper.

It can be done on the disc side without removing the wheel. I have done it, but be prepared to seriously bend the new spoke to a 'c' shape when putting in through the spoke hole without putting kinks in it. Then straighten it as best you can when screwing it in at the rim. It will straighten out...

I like to slightly squeeze the glue tube until glue is at the top to remove any air when putting the top back on and this seems to help stop my glue drying up.

For offroad it has to be mid drive for the gearing. I might end up reusing the kit on this bike yet, on a smaller bike.

As per my eMTB build thread I have decide the bike is too large for me so have the choice of sell the bike built as is or strip it all down and rebuild with a small size frame. Medium 18" frame size, 27.5" wheels, aprox 31" standover height. All appears to work as it should but you can come and...

Nealh has just reminded me I've got a 36v/48v KU123 30a controller full kit buried in the garage. Those controllers don't use LCD and worked better with throttle rather than PAS . I could sell it all as a kit and bet it would blow the socks off a fleabay DD kit.

Yes, a few years ago though. Here's the draft before printing. I could send you the document if it's any use.

New Q128H 36V 800w 201rpm freewheel version originally purchased from BMSBattery laced into a 700C all black rim. Been hanging in my garage for a few years and have decided I don't need it so may as well sell it on to someone who can make good use of it. Has a 250w sticker, 145mm over locknuts...

Chain Reaction Cycles sell quality rims. Ensure you get a rim with the correct number of holes to suit your motor and front hub which may be different. It shouldn't be £260 if you just replace the rims, just get rims with the same ERD size. and rebuild with the current spokes.

After only doing a handful of miles I have decided the medium frame is too big for me. The choice I have is sell as is without a battery and build again from scratch or strip it all back to the original mtb and sell the bike and put the electrics on a small size frame. Anyone interested in it as...
