    Touring on a Wisper

    Easter Hi Frank, thanks for the report, I am very jealous! I gave up my 905se to a customer and am awaiting one of the new batch for myself. But as the first container only has 70 units, 25 of which are going to the Electric Transport Shop and many others are on pre-order I may have to wait...

    Why can't you derestrict a Whisper 905e?

    Speed Sorry guys it won't do 22mph without input from the rider and the only switch on the 905e is the on/off switch for the throttle control. Best regards David

    Why can't you derestrict a Whisper 905e?

    De restrict As always Flecc is spot on, there is a restrict on the later 905e's, it was put on to reduce the speed from 17 mph which is illegal in the UK to the legal limit of 15.5mph (25kph). On the new SE's the de-restricted motor will still only achieve 20mph without power input from...

    Getting broken spokes fixed

    Hi Mark, we have a stock of new spokes coming in our April container, in the mean time I would do as we do now and take Frank and Ian's advice and get them from SJS they are fast, efficient and not expensive. Are the spokes on your 905e stainless steel? Best regards David

    Wisper battery charger

    Chargers Thanks Flecc, it's amazing. Especially your earlier point about the house hold kettles. If you had the will and a couple of screw drivers you could tap in directly to your household electricity through a socket. :D Best regards David

    Wisper battery charger

    Lishen Hi John The problem with the Lishen batteries was not the cells or internal software as we originally believed but simply the connections between the cells breaking down as people bumped their bikes up and down curbs or through pot holes in the road. In some of the batteries the...
