We have moved away from the point.
The modern powerful crank drive bikes need stronger e-bike specific chain, chain ring and rear cassettes. These do not need to be overly expensive. 7 widely spaced gears would be enough for most applications, geared in a way that there are no less than 14 teeth (The more the better) for the highest top gear and with a large enough bottom cog to be equivalent to a current 36 tooth bottom gear.
You can achieve this yourself by putting a larger front chain ring on with a cassette that has a top gear with more than 11 teeth and a 36 tooth bottom gear (or larger if you can find one) to compensate for the larger chain ring.
I recently replaced my front chain ring with the next size up, two more teeth bigger and a cassette with a 12 tooth top gear and this has been noticeable more resistant to wear than the previous 11 tooth one with still a low enough bottom gear for climbing off road.
However although it has lasted longer it has still been susceptible to jumping under load as my mileage has increase.
My only option is increase the size of the chain ring again (42 teeth) to have a 14 tooth 8th gear to achieve my 20 mph cruising speed with a probable mostly redundant overdrive cog above, ( I don't want to cruise at more than 20 mph ), but on my 9 speed set up the largest bottom gear I can find is 36 teeth which may not be low enough for off road climbing when combined with a yet bigger chain ring.
It would be a lot better for a manufacturer to make one I could buy!
Do the manufacturers actually ride their bikes? Surely if they did they would be aware that crank drive bikes need a more robust drive train.
It cannot be that hard to get one made. Come on Col, steel a march on the opposition and grab the niche that clearly exists. After all good customer service is about providing what the customer needs and we need this.
As D8veh has said my previous hub powered bike had no chain, chain ring cassette wear issues as the drive takes pressure off these components rather than adding to them.
However I love my crank drive bike and have found this to be the only serious weakness and stronger e-bike specific cassettes and chains would sort it. Nuff said,Rant over.
