Probably Bosch SX, they seem keen to claim it as "full power".

Found a thing on the Bosch site that lists KTM etc. But this doesn't include Whyte so I'm assuming it isn't a complete list. https://www.bosch-ebike.com/en/service/ebike-models#category=112&motor=302

I had an issue with my combo of disc, hub and magnet. Just put a small neodymium magnet on the disc itself to test and when I was sure it was in a position that worked glued it on. I carry a spare magnet with me just in case it come off and gets lost but been fine for a year now. Hope this...

Designing bike parts is my job. Can't show the ones I did unfortunately, but picture of the test bosses I printed to check the spline fit are below. I use Solidworks which is kind of the standard in the bike industry but the files I send to the 3d printers (in China, using online upload links)...

Bosch SX motor was released/announced a little while ago now. What bikes are there using it so far? I know the Whyte E-Lyte is out. Any others?

More expensive than the forged cranks but not ewings territory either. Currently paying about 60 cents (US) per gram for Aluminium. With a short crank and good design to make full use of the printing you can save a lot of weight. The ones I did were about 275g for the pair so with shipping just...

I have successfully had 3d printed aluminium arms made to fit the spline well. You can do hollow section and just the length you need that way.

Sorry for the delay. Road cranks are a tiny bit better for your purposes. From the 36mm raised boss around the axle the scallop on the road cranks extends to 121mm. On the MTB cranks this dimension is 124mm So from axle centre should be 139mm and 142mm respectively. The end of the scallop is...

Friend of mine just picked up an Orbea Rise M20 (carbon one) with some nice component upgrades a couple of years old for £2k. Seems like a very good deal to me. Yes, there isn't any warranty but at that price he can afford a few fixes if needed. The price drops for new bikes have really squeezed...

Can do if you really want, fairly sure the road have a shorter scallop but don't think there is much in it. The main concern is that there isn't already a pedal hole too close to where you need to put the new one. Going from 175mm to 150mm only gave a hair over 10mm wall between the original...

Maybe in Texas. Unfortunately on this little island there is now almost no-where you are allowed to ride off-road, nearly all the B.O.A.T.S. in the Peak District now have traffic orders on them banning anything with an engine. Haven't ridden my motorbike since getting the eMTB, which I can ride...

Knee degradation not so much though maybe? Plenty of longer cranks to choose from for that motor.

I broadly agree. And I don't think it would be unreasonable to expect longer warranties. I'd like to see every company list all the parts as spares with clear prices and compatibility notes. This would also let riders upgrade which could get them more sales. It might well end up being a case...

The motorbike frame is robot welded together in one size in 10 minutes from a dozen or so parts made from relatively cheap materials. The typical carbon fibre emtb frame is made in 4+ sizes, laid up by hand in custom tooling from hundreds of panels from relatively expensive CF prepreg.

I managed to get 2nd's which are fine. It's only aluminium so you can probably get away with those or give them a quick tickle on the grinder to add a bit more taper. Good luck.

My phone does this too. When it gets down to 15% or so that last 15% goes much faster than the first 15% did. When it gets to 5% it is moments from shutting down. This graph isn't the best but it gives an idea. That last 15% or so is far from linear and predictions are hard to make. You DO...

I got the taps from a little tool place in the UK called Tracy tools a looooong time ago, but you can get them on ebay and from Amazon usually (at least in the UK). You want Left and Right hand version of 9/16" 20 tpi BSC (British Standard Cycle). Cranks were from an online retailer (bike shop)...

At this point, you just look like a Troll. You started this thread with a single sentence and refuse to back it up in any way shape or form. None of the bike brands have a monopoly they are all competing for the same pie. Same goes for motor and battery manufacturers to a certain extent. If you...

Sorry must have missed the "data", could you re quote it please?

I work for a bike company yes. But we don't currently make any ebikes but I have been working on our first for a while, hence I know what the parts cost and so can make a reasonable estimate of what the margins are like. Emtbs are much more demanding than city bikes.
