Love it!

easy peasy on the flat. But direct drive motors are not good on hills. In keeping with low budget builds, for speed, go for 48V 750W BBS02, for climbing hills at high speed, 36V 500W BBS02, for good all rounder: 48V 500W BPM or 36V BPM if your'e skint.

No, I'd do exactly same.

yes, you should. You can make some like this one on the woosh zephyr-B:

I understand now. The difficulty is for the existing s-pedelecs as sold in Germany - but stalkingcat prototype is built to L1e-B from the ground up.

sorry, I meant anyone wanting to build an s-pedelec only has to get a CoC for L1e-B same as the Dichao FT. I saw one second hand on gumtree for £400 http://www.gumtree.com/p/bicycles/2012-electric-moped-bike-scooter-dichao-ft2000-saiting-ego-street-scoota/1089967834

there are precedents with regard to registration and insurance for e-mopeds. The bike is Dichao FT, imported since 2010, insurance £90 a year by bikesure.co.uk I've seen plenty of examples of Chinese e-mopeds with certificate of conformity. There is nothing to stop Kalkhoff to get a CoC for L1e-A

I can't see why an s-pedelec cannot be registered as a moped.

it ought to be straightforward according to people who sell e-mopeds. You fill in the form, attach the certificate of conformity, pay the fees. After you get the registration document, you can get a number plate made and insurance. Some even offer to pre-register it and fix the number plate on...

if you're stuck, try woosh. I think it's the same length as on their Sirocco bike.

cwah's requirements for a two seater elmoto in London is typical. I believe there is a market for this sort of bikes, but selling price has to be competitive against similar ICE machines. I think stalkingcat's prototype will be around 35-45kgs, if he ever manages to work with the motor from...

the vboxx in his new prototype is a very expensive piece of hardware to enable an elmoto to be pedalled like an e-bike. You don't see e-bike/elmoto refined to this level anywhere else than the Stealth Bomber.

I actually believe that there is a commercial future in what members like stalkingcat are trying to achieve, a flexible e-bike/elmoto. The route to type approval is not that onerous, provided that the product will sell in sufficient number - about 100+.

that's pretty mean. Why do you have to make this point? he's not selling anything on this forum, unlike morphix.

Col, stalkingcat builds prototypes. Are you saying that he should not build prototypes? This is the £1,000 bike he built and sold. Read it, you'll understand the man. http://www.ebay.co.uk/itm/Electric-Bike-set-at-3300w-72v-Infinion-controller-winter-tyres-AMAZING-/141563649145

hybrid car technology illustrates what MPG and range can be achieved when a small petrol engine is supplemented by electric drive. The battery of new BMW i8 on Top Gear tonight has only 7KWH. It may be possible to transfer this technology to two wheelers, we need more work done on this now. I...

I don't think you just 'dive in' - your previous bike is superbly built, the current bike will have better riding position, lighter, more power and more bike than the previous one. The bike after this one will, I am sure, be even better still.

IIRC, cwah prefers his BBS02 48V 750W kit before he broke it.

it difficult to match the ride quality of a DD motor at 72V, certainty not the BPM. I reckon the BPM won't melt at 72V for 10 minutes.

this is one occasion where the throttle can be very useful. It lets you concentrate on the steering. It seems to me that you'd need a more sit up position with the handlebars a little nearer to your shoulders.
