All KT are by default current control/imitation torque, as and vfr & I have before you can have speed control by changing P3 parameter.

When cycling to work I wear hi -viz and to some drivers it doesn't seem to make any difference. If I go shopping then I have a lighter blue rain jacket or if colder like now a black and dark blue jacket, personally colour matters not.

With most good 250w hubs one can throw 20/22a at them for more power though one needs to use the extra power sensibly, for your needs you need a 201rpm hub. 48v would be favourable over 36v.

The pic of the motor extension wire looks like 3 pin and would back up the ZWS code as square wave.

ZWS after the KT24,36 or 48 etc, means it is a square wave controller. SVP after the KT v type means it is a sine wave controller. Confirmed by checking motor wire connectors. The other other figures/numerals are gibberish but will relate to Julet or SM connectors and programming/software as...

A bottle battery or a Hailong 2 side off battery may fit in the triangle, obviously measuring is critical. A tringle mount will be far better then a rack mount. H2 battery you need 365 x 106 height to be able to fit in the tri area. Hailong2 Battery 36V12.8AH Panasonic NCR18650-BD Li-ion...

Sell it and buy again correctly. For your old frog battery simply get it re-celled at ebikebatteries .co.uk.

It is clear in one post where the seller is but not the the potential buyer.

One would think driving any distance to buy a used/2nd hand bike would be frowned upon esp if you are ANPR'd.

Impulse 11 was introduced 2014 so the year needs to be more specific, consideration should be given to battery age. At seven years one will not know for how long it will continue without degradation.

For a bike diyer who can build wheels ( a few of us on here can), it would be a pretty cheap buy at less then the £200, as has been mentioned if one rim has gone the other may not be far behind so a £200 repair bill.

Yes some gears will be unobtainable with 2x set up with mid drive, cross chaining means not all gearing is accessible, I found low gears only available with the small ring and vice a versa though all should be usable in one way or another.

I used a std KMC 9 spd chain and derailleur.

It is terminal and unsafe to ride in that condition. When the rim goes like that, it is because the brake wear is through B/W line. Once the rim is worn too thin it breaks up or the tyre pressure blows the rim. It will need a new rim and spokes tbh .

Think I would agree with vfr Blue/Gnd & Yellew/sig.

3kw hub just to go 15mph pull the other one, doesn't make no sense at all.

Mike I think it's the brigade who say they won't ever be caught on an ebike (roadies)as it is cheating, but they don't mind so much if it doesn't shout ebike. Much in the same line as those who think TS drive is like riding a push bike when it is totally the opposite and has some 300% more...
