...Scunthorpe?

Nope! Some new town in the Midlands , Telford?

Not really D8veh

I actually thought that the question was best road bike, as in drop bar road bike.

If it is just the best bike for road use, I already own and ride close to it
My GLR trike with BBS01, light, very fast, superb braking and handling and can climb anything.
If I was healthy I would probably swap out the drive for a torque sensing one, but then maybe not as it would be hard to improve.
I dont think I would ride it in London though as my head is around knee height.

Riding the Greenspeed in London! Eeeeek! Soon be looking for you under some artic trailer, mind you you might choose to take that route as a short cut.

I reckon it would be this :

Fitted with this :

http://www.vivax-assist.com/en/produkte/vivax-assist-4-0/vivax-assist_4-0.html

I don't know if it would be compatible, but if it were, would be a total £5,800 price tag with the bottle battery. I reckon it would make a lovely package you could happily go light "off-roading" on whenever you wanted.

The US-supplied comp carbon is a grand less and probably far more sensible as an all-rounder with 105 instead of Ultegra, but it's not available to the UK market.

Something to get me across Europe - a bike which could be folded easily to fit in a car or bus boot or plane hold, it have a battery array capable of 100 miles a day, and be comfortable and carry panniers - and somehow resist all attempts at theft.

Xiongda 2-speed or Bafang CST 250w, 20"-24" wheels, 2x 15ah batteries. Oh, and the capacity to alternate between S-pedelec and ordinary pedelec modes, to enable quick progress on roads when things get boring, or more serene progress through scenic routes.

It seems that we think alike. http://www.pedelecs.co.uk/forum/threads/the-ultimate-road-e-bike.19648/#post-244500

I'm also a fan of Specialized bikes, but would probably go for Canic CXC to keep the orange colour scheme.

Ok, just a bit of fun: If you were designing an Ultimate E-Bike (legal), what components would you use if money was no object ?

Wheel size, motor (crank/front or rear hub), which motor, what system, front or rear suspension, gears..how many, what set, seat, post, frame material and design

I guess there maybe a Haibike already out there with many of the best components but I bet it could be improved.

I was thinking about this (again) late last night and I came up with 3 options:

1) Bosch crank drive is said to be good, but Panasonic battery is said to be better, so pair the 2 for better performance.

2) "Ultimate" - the last/final. I guess we are looking at one of Martin's fiddled Haibikes here, but with no brakes! This would truly be the ultimate bike as the rider would not get off alive again once they had got up to speed - especially in traffic - and so it would be the last bike the rider every used!

3) Legality is an issue here - so we are going to run this in a country with not legal restrictions on the e-bike. Money is also no object - so this will be a bike funded by many national governments as part of a research into renewable energy. The premise is this:
a) Throw money at nuclear fusion until we can sustain it for long enough to provide power.
b) Throw more money at it to downsize the reactor to "battery" size and mount on a bike - this will of course necessitate removing lots of vital safety procedures and during the testing of this, it will explode. The resulting explosion is self perpetuating and destroys the planet (due to it being a fusion reaction not a fission one) giving us the last e-bike as no other one will be created! Making this the ultimate e-bike!

Final pondering:
Is there a legal - restriction on using rockets as a form of bike propulsion? If we used the electric battery to convert H20 to H2, we could probably argue we had a rocket powered e-bike if we drive from the rocket and "charge the rocket using the battery" - I know it is dead weight but it is fun thinking about!

I wasn't especially drawn to Specialized in particular - mainly due to their inflated 'big brand' price tags and MAMIL associations .... but ... the combo of that particular bike ticks all my boxes - especially hydraulic disc brakes, ability to take CX tyres, less aggressive 'racing' geometry than a CX without becoming a road bike. If they hadn't excluded it from the UK market, I would almost certainly have bought a Comp Carbon (which is about a grand less than the expert carbon and has 105 rather than Ultegra so less "precious").
I'm a big fan of grey/black bikes ... not one for white or bright colours, so that was a bonus for me. I think you've caught the KTM bug with the orange thing

by accident I may have stumbled on it - I had an old b'twin triban 3 (9.8kg) on my scale, and I just purchased an oxydrive kit (13ah - in reality probably 250w with its max 15A 36v controller) which weighs 7.8kgs. i'm tidying up the install and verdict still out on hillclimbing and cruising speed, but as a non muscular sort (60kg), I found myself astonishingly easy able to pick it up one hand (17kg)

77kg all up! It's going to fly. I'm jealous. With 700c wheels, 28 mph should be achievable.

 

[Gubbins]

Pick your prefered 8kg road bike drop a Vivax in and sorted, a sub 10 kg assisted bike.
Low powered but on a light road bike it would be magic on steeper hills, the current version is apparently very quiet.

Just looked at the video.. Wow, thats what I call walk assist!!! I think I might forget the Copenhagen wheel and see if this would fit my boardman

 

[Deleted member 4366]

You know it's only 180w maximum from the battery, which equals about 120w real assistance?
