Which bike has the longest pure power range?

[pedestrian]

I currently get about 10 miles from my Powabyke X-byke (I weigh about 14 stone).

Are there any bikes which would do more than this on pure power?

 

[bert11]

17 miles on mine, 95%+ power only. Details in sig

i am expecting about 70ml on my whisper 705se sport 200w with 20ah battery, but have never been far enough to run it flat.

Nearly all of them because thats quite low.

The bike with the biggest battery will go the furthest. Multiply the battery volts by the number of amp-hours and the higher the number, the further it will go. Other things like weight and motor/controller/drive-train efficiencies make a small difference; changing knobbly tyres to slicks makes a worthwhile difference, but, if you want to go far and don't want to pedal, get a big battery, or carry a spare or two.

When I was doing my research, the LifeCycle showed up on my radar for pure power/range:

About The LifeCycle Electric Mountain Bike

"it has the Hi Torque Xtension motor that is exclusive to LifeCycle. No other electric bike has this special motor. And this motor is powered by a Lithium 37Volt 17Ah Battery"

I am a bit confused now... I thought the ah of a battery determined the range.. By what you say a assume that wh is the real deal..

This means that a 36v 10ah (360wh) battery will have significantly less range than the 48v 10ah (480wh) battery, running on the same wattage ofc..

I am asking this because I want a 48v 10ah battery but alby has only the 36v 14ah available.. If the above is true then having the 48v gives roughly the range of the 14ah one but with the extra plus that you can squeeze the battery to commute in greater speeds when range is not needed, right?

Hi.
Take a look at this thread: http://www.pedelecs.co.uk/forum/electric-bicycles/6883-lifecycle-electric-bikes-anyone-have-one.html

Yes wh are the real deal as its a measure of the energy capacity of the battery. Range is also determined by what type of drive system you have so a larger wh battery may not always give you greater range when comparing different drive technologies. However, given the same drive method, then yes the more wh you have the further you will go given that all the other variables stay the same

Also, there's an argument for the higher voltage as the losses will be less for a given current draw from the motor.

I see... Thanks for the insight, I guess I should wait for the 48v 10ah battery to arrive then even if the waiting is killing me...

Wow, that's impressive. How much do you weigh?

However, wisper only claim "up to 56 miles range" for the larger battery. What makes you think you can get 70?

That Wisper claim is for their largest 14 Ah battery, so for 20 Ah their claim would be up to 80 miles. Theskip1 must be using another battery to get the 20 Ah.

=--------its 20ah

thats right i am using a 20ah vpower battery. I had to alter the frame to get it in. you can get an idea from the pic. in case your intrested its a pic of the old croydon airport looking east.

Croydon's London International Airport was great, with it's traffic lights stopping the traffic for airliners to land on the main runway that crossed the road. I don't think many cyclists would want to jump those lights!

Heathrow is boring in comparison.

Is there a demand for 20Ah batteries?

Our new generation bikes are 16Ah and we felt that was about all the market demeaned, we can fit 20Ah but would anyone pay the extra?

What would the extra cost be David ?

And how much advantage would it give ?

What about extra weight ?

But, in principle......YES PLEASE

Hi Lyne, I am off to the BEBA Parliamentary e-bike day in a few minutes (terrified, as I am presenting to a bunch of MP's etc in the House of Lords committee room 6).

I will reply in full tomorrow (and your pm), but roughly.....

20% more range and weight.
£100.00 more cost.

All the best

David

Best of luck David......go go go......speak later

Thanks Lynne, it is good to have a chance to put the electric bicycle argument to the power that be!

Best regards
