They all say 15 mph but really, can you go this fast?

will this design increase the need for regular maintenance and wear to chain and gears?

Scientific curiosity (which I applaud) aside, Dmiall put it so simply and elegantly: The tests are obviously designed to test the bikes on average conditions.

Is the Bosch drive system available for DIY projects?

flecc, if I have offended you, I am sorry and apologize for it. Frank and NRG also made the point that EN15194 limits the ability of the new specs in hill climbing, the key point of this project.

So why are you disputing with me what you approve with him? 10mph tested only on 20 metres, it's not a hill.

It's not a challenge, I only made a practical observation that all manufacturers have access to similar technologies that are limited by EN15194. As Frank pointed out, you can only climb more hill if you void your test certificate. Furthermore, what can come out of the motor depends on the...

My point is, if you take two riders, one with Kudos Carbon King and another one with Kudos Sport (the one I wanted to buy and might still do), both will race from A to B. The one with stronger legs will win on any length, with or without hills. Manufacturers are hemmed in by stupid EN whatsit...

Kudos uses Bafang 250W motor, if they overclock the controller, other manufacturers will complaint to trading standards. They wouldn't do it anyway because it's illegal. You can do anything you like with your bike, that's why I wanted to know how you can knock them dead. All e-bikes as I...

Andy, if you are climbing a hill, you will need a sustained output from the motor. As with car engine management, the peak output of the engine may be twice of its RMS but if you run the engine at that rate for eny length of time, it'll burn out. My solution for improving uphill performance is...

current e-bike standard 250W motor would limit what the bike can do. The physics formulae: W = F x d, W being 250W + rider's own physical effort, means that if the motor is geared to lower speed and higher torque, the rider won't go any faster uphill.

Hi Jerry, I saw the e-Brompton at evans cycles a couple of months ago and was very impressed by it except that it has a very short wheel base. In your experience, does its very small size make you feel unsafe on say Trumpington Road in Cambridge?

Is it true that you can charge up the battery in just 30 minutes? if so, why aren't they more popular?

fatboytrig, just a quick question, can you tell me the ratings of this bike's battery and motor?

scottyf: I think you are right, with front wheel drive, the bike does have effectively two wheel drive. Which model would you suggest scottyf? should I choose one with throttle or not?

Scottyf, bikes with motors in the front - are they less stable or less manoeuvrable when cornering?

Thank you Andrew. By the way, your bikes look absolutely fab!

Is LiNiMnCo04 a better choice than Lipo that most e-bikes seem to have though? does it charge faster or is it more reliable? the one that caught fire (Lithium..... really hot batteries thread) - which type of chemistry is it?

What is the difference between the Oxygen LiNiMnCo04 and Lipo? is LiNiMnCo04 better?

Can anyone tell me what's wrong with the Sirocco?
