Brilliant Mike, nice one! This project bike has completed all the proving trials, but there's a specific reason, nothing to do with the project, why I'm holding off announcing it yet. Meanwhile there's three tiny things to do to perfect it which I'll do in the next couple of days. Then I'll continue to enjoy it for a week or two before going public.
I'm saddle sore at the moment having completed 67 miles on two and a quarter charged batteries (2 x li-ion, 1 x NiMh) today, plus a photo shoot at a local park ready for the website. All three batteries are humming away on three chargers at the moment ready for tomorrow.
This is much more than an assembly of parts though, involving frame bending, shaping, and welding, motor modification involving brutality with an angle grinder amongst other things, some parts I've specifically made for the job, and one part I've had made out, so it's not something which will be generally undertaken in many back garden sheds.
Meanwhile here's some morsels. Sees off a restricted Torq without any trouble. Cross country average within 1 or 2 mph of a derestricted Torq in hilly or moderately hilly country. Can climb anything with ease, a ten year old could climb a long 20% (1 in 5) with little effort at nearly 7 mph, and I can climb it seated with minimal effort at nearly 9 mph. Tows my huge trailer up that long 20% at 6 mph. Li-ion range averaging between 30 and 35 miles for me in the hilly North Downs, over 25 miles if I make no effort at economy, a younger rider than my 71 years should be able to do better.
And it's completely legal.

What to go for? I say the Wisper 905
Just to add to my email yesterday. I have a lot of time for the Wisper and the Company. Whenever I have rung up the company they have been very helpful, as I said before, interested in what you have to say, and they want to help, and provide a service. That means a lot to me. Another electric bike company i purchased a bike from, should learn from that. When you spend a lot of money on a bike you expect action when something goes wrong. Not to take the bike away for weeks and when you ring up , they still haven't looked at it. Also when I received that bike new, (cost £1200) the gears didn't work, the company in the UK hadn't even checked it when it had arrived from China. Another friends bike arrived with two punctures.
However with the Wisper they check and adjust before sending them out. I'm very pleased with the Wisper 905, I've done nearly 150 miles with it. Its light, very smooth, brakes actually stop you. Get a test ride you will be very pleased.

That's great Grandad, thanks!
I wish I had a shed though , I work under the greatest of difficulties at times in these projects.
When? A week or two maybe, there's someone else who has something to announce and I want to leave the coast clear for them first.

Yes, I have been making quite a lot of noise Nigel!So its Mr flecc making all that noise all through the night biff bang bosh
You will probably be disappointed at first sight of the bike though and wonder what's special, but it's the universality of what it does that counts, and how it was achieved that's of interest.

Hi flecc
i will be buying a second bike this year for travel to work 16 miles each way i have done the journey a few times on my torq and it done the miles fairly easy as its a fair distance to travel i dont want to wear my torq out bit sad i know so my question is would the easy LIV be a better hill climber then my torq. Many thanks fleccster.NIGEL

Yes, definitely Nigel.
The motor is normally internally geared and has far more hill climbing capability. On motor alone, the Torq can only manage a 6% hill, but the Liv on motor alone can climb 10% without problems. The torq measure is for my weight when it was 75 kilos, but it shouldn't be too much different for your, which I've an idea from memory is about 16 stone/ 102 kilos? Forgive me if it's less than that.
On the rider side, the 46" low gear of the three speed Liv is miles lower than the 58" low gear of the Torq, so the rider's hill climbing ability is also much better on the Liv.
Add the two together and you'll find the hills dead easy with the Liv, but not as fast of course.

Whereas I'm trying very hard to wear my Torq out, just for the excuse to buy an f series - but the darn thing is so well made.. . . . i dont want to wear my torq out

Whereas I'm trying very hard to wear my Torq out, just for the excuse to buy an f series Well that seems like a good excuse i think my next purchase will be the Liv and thinking further down the road would there be a problem in changing from 3speed to 5speed hub gears your thoughts most welcome NIGEL.

Well that seems like a good excuse i think my next purchase will be the Liv and thinking further down the road would there be a problem in changing from 3speed to 5speed hub gears your thoughts most welcome NIGEL.Nigel, according to the Shimano EU website there is no 5 speed in the shimano INTER series hubs, the nearest being the 7 speed INTER-7. As far as I know you would need to stick with the the Shimano INTER range to retain compatibility with the hub brake, of course if you were to change the brake you could fit any hub you wish.
A complete replacement hub would be required as the gear internals are not interchangeable therefore the rear wheel would have to rebuilt, a job many people would prefer to have done professionally. Alternatively it may be possible to purchase a 26" wheel complete with gears.
Also I think the handlebar shifter would need to be replaced.

Just means the cost of the brake hub gear and new control plus a wheel build Nigel, around £200/£250 total. I think you'd find it's just not necessary on the Liv though, those Hampshire hills should be easy enough on the 46" low gear.
With the Liv's 85" top gear you should be able to pedal up to about 20 mph at a fast cadence of 80 and about 23 mph at a cadence of 90, that's very fast and the typical pedalling speed of fit club riders on their drop bar bikes.
With an SRAM P5 hub with 17 tooth sprocket you'd have gears of 37" to 94", so in top you'd get about 26 mph at that 90 cadence. These speeds would only be useful for downhill help though, you'd be unlikely to be able to pedal that e-bike's weight to that on the flat.

I don't think there's much chance of that, there's a few gears in the motor subject to wear but I'd expect them to last an enormous mileage, the battery will deteriorate whether used or not and everything else that may wear is bog standard bike bits, cheap and easy to change.
