@ robint. The new crank drive bikes are a lot more powerful than your old motor, derailleur is definitely better than 8-speed hub gear.

Well I got mine as a back up for £100, but wish I hadn't bothered. I had been spoilt with my Khalkhoff but that was 5x the Tesco price. I strongly recommend that you test ride one of these before buying and see if you can managed the quirky front hub drive plus derailleurs. The power is delivered in response to crank speed only not torque. Its coarse and no good for low speed manoeuvring - like on pavements. I disabled it and used it in twist-go mode

If you only wanted to do short trips on flat roads - well? So why bother with an e-bike (they are heavy 20kgs) so not luggable even though they fold up.

Get a Viking 6G shimano ordinary folder, instead (11kgs) ca £150, good value and its my back up of choice
many thanks, I was hoping one could adjust power so it wouldn't be all or nothing? it's a tricky thing choosing an ebike, I have an oxygen hub drive im very happy with, I tried a friend's woosh santa ana (chinese crank drive with movement sensor)over the weekend on a long cross country ride, which was also OK, and ive tried a kalkhoff impulse 2 a while back, which was also fine - but their all really quite different animals and I find I couldn't choose a single one, all different relative strengths and weaknesses.

Yes understood. I was referring to the uk regs which said that power was limited to 200W, apparently we are now in line with the EU at 250W, shows how out of date I am.
Not very much though Robin, less than 5 months. The new law only arrived on 6th April this year.

Yes Its horses for courses and derailleur is more efficient with greater gear range and most suited for touring not for my low speed town/ pavement stuff, but funnily enough I managed well on my 6sp der viking 20" folding pushbike. Very nimble
