Funny you should mention that, it was a part in that mechanism (the sprag clutch I think) which failed in my Wisper.
Were you or local fixer able to instal a replacement OK ?

The bike was (just) in warranty. I took it to Wisper HQ in Kent and they replaced the entire motor in the hub. I don't know whether they had no spare clutch in stock, or whether it was just quicker and easier to swap in a new motor.

Good to know they have good after sales service.

I’d be quite interested to hear and understand more on those improvements, please. Whilst I much prefer the simplicity of none electric bikes there may come a time when I need assistance - it’d be wise to prepare for such and it’s far better to ride with assistance than to (have to) give up riding.
Best bet is to keep an eye on websites such as https://www.cyclingelectric.com/ and https://ebiketips.road.cc/ (which is an e-bike sub-site of road.cc).

They'll pick up and report on far more e-bike tech stuff than anyone on here could manage. It might be worth looking out for e-bike demo days - some of the magazines and websites run events (usually in May - September) where a bunch of brands will get together at a closed circuit or an outdoor velodrome and do a day or a weekend of test rides. Here's one such event (actually a series of events) from last year so I assume they'll be doing a similar announcement early in 2026:

Note that to get the maximum benefit out of them, most e-bikes need the user to have a smartphone for connection to the motor and the tuning app.

Woosh are currently out of integrated controllers for their downtube batteries. After reading up on it I have decided to put together the bits myself using an MXUS XF08 freewheel motor I have from an incomplete project and with a 22A KT controller which uses current control rather than speed control. (But it does need configuring.) I will leave getting the battery and holder until I have all the other bits fitted and cabled up,

If the fitting of a rear hub motor comes into the equation then take a look at the latest offering from Woosh bikes of Southend - they are introducing a rear hub system (currently 26" wheel but 700c in the offing) that incorporates a torque sensor into the cassette freehub (along with a speed sensor). The controller is in a seat pack battery so a very neat installation with one cable from the rear hub up to the battery pack and a 2nd lead to the handlebar controller.

If you pop over to the pedelec site you can read more about it here where a special intoductory offer of £349 is currently available.

That's a great idea having the torque sensor built in to the hub -- means no brake sensors needed if the torque sensor cuts immediately no torque is sensed which is very possible because unlike a cadence sensor it doesn't have to average rotational pulses to determine if pedalling is happening or not. Although I see there is a speed sensor incorporated too.
Great price too -- the other kit suppliers will need to follow this to compete.

I might have gone with this but I am invested with the MXUS motor and KT controller now. But this looks perfect for a recumbent bike or trike.

Anyone been tempted. ? Is the rear wheel rim disc only or compatible with rim brakes. ?

Yes I'm tempted to get this for my ICE recumbent trike which has a rim braked rear wheel. The photos on the pedelecs forum show the hub with a disc fitted.
