Finally selected and ordered: Cube Touring Hybrid One 625 2024 Electric Bike, from Winstanleys (good sale price) (same spec except bigger battery). The Kalkhoff in the right size disappeared from the on line sale, and anyway the Cube offering looks a better deal. Thanks all for advice and...

I have looked at 48v TSDZ8 kit data on line briefly. It would take me some time to get familiar with the terms and evaluate. It would clearly be fun to do and a lot cheaper than buying a similar spec bike, but it sounds like the power output (>250W) and the availability of a throttle mode...

A Kalkhoff Entice 3 move for £1999 looks similar? Bosch performance line smart 75 Nm, 9 gear ratios, disc brakes, all frame sizes, from vansprint.co.uk.

Interesting about the controller. I looked at some kits on Amazon, including Woosh. Looks like there could be trouble getting stuff to fit a given bike, and waterproofing things, and having it legal, and battery safety acceptance while touring ... I do have a spare push bike I could adapt...

I sort of assumed there would be a practical stall threshold torque for a controlled motor system, with max current from the given battery at min reasonable rotation speed. Near that point the system would be non linear and the motor and control components would get hot, wasting power and...

Thanks for the info on touring. The Agutta uses the 50 Nm torque drive, surely the weakest is the 40 Nm, requiring the widest gear ratio for a given hill? The hill ability would depend on the lowest gear's ratio, rather than just the number of gears. I have read that some complain that the...

I see I can get a Kalkhoff Agattu 3.B Excite 2021 for £1900 delivered and mostly assembled. It is tempting, though possibly OTT for my expected usage. I think that you have to charge its battery with it in the bike? Can the 500 Wh be replaced with a 625 Wh battery when it dies? I am also...

"ease of maintenance and customer service / long life" would be good things, though not obvious from this supplier. I would expect a Bosch motor and battery, and a thrust sensor as a starting point normally. I have not seen the make of motor or battery they use mentioned elsewhere, and what on...

Well I used to work as an electronics engineer, before I switched to being a mathematician, so the electrics and indeed the life stats should be within my grasp :). Clearly most bikes in the £1..2k range would be usable, but I want to make a rational choice - apart from anything else it is an...

Hi, at age 76 my cycle rides are becoming limited by rubber legs, so an ebike might be sensible. The Which best buy Trek Verve+1 at discontinued price £1444 with 500 Ah battery looks tempting. The Chinese Fiido C11 Pro is cheaper, nicer looking, similar specs, with a frame mounted battery and...
