May 6, 20178 yr I've been reading a lot of reviews on bikes and it seems some people quote very impressive range on bikes with relatively small batteries. For example a few people state miles of around 40-70 on the Crossfire E which only has an 11ah battery. Are these individuals just very lightweight and fit and only on flat roads?
May 6, 20178 yr I've been reading a lot of reviews on bikes and it seems some people quote very impressive range on bikes with relatively small batteries. For example a few people state miles of around 40-70 on the Crossfire E which only has an 11ah battery. Are these individuals just very lightweight and fit and only on flat roads? .. there are any number of explanations. If they are riding a legal bike above 15mph, they will not be consuming electric power. If they are riding slowly at say 8 mph, they will not have much wind resistance. If the tyres are properly inflated and they are lightweight, then they will have less rolling resistance and finally some may not be truthful.!
May 6, 20178 yr You can get infinite range if you pedal hard enough. You also get good range if you turn down the power, use a lower gear and go slower. I've had ranges of 20 miles and 169 miles from consecutive charges on my bike. It just depends on what I want to achieve from my ride, like whether I want to get to my destination as quickly as possible or get some exercise and enjoy a ride in the country. Any statement about range is completely meaningless in terms of evaluating a bike. The only thing that matters to you is how many watt-hours are in the battery. The more you have, the further you can go. The more assistance you want, the faster you'll use them up. The rate that you use them up is personal to you and your rides. What anybody else gets is completely irrelevant. A light bike with a low frontal area, thin tyres and thin forks will be more efficient than an MTB-type bike, especially at speeds above 12 mph. At 20 mph the difference would be massive.
May 6, 20178 yr I was riding my borrowed Scott, with Bosch motor and battery, and noticed that the range seemed to increase for the first few miles. I assume that this is just the battery warming up and then giving a little more voltage? Or is something else going on?
May 6, 20178 yr I guess like a car the range is calculated on current usage,i remember filling up my car once and then going downhill,i was getting around 85mpg on the computer, going home uphill it soon came back down to 42mpg,as for long range on an ebike,some people use level 1 assist and even switch off assist at times to extend range, it looks good on paper but its not real fun,there is not much point having a motor if you are not going to use it.

Are you talking about manufacturer claims? Or their riders' claims?

May 7, 20178 yr Riders claims Then Dave has about nailed it in his response above. Everybody both rides differently and with different intent.
May 7, 20178 yr Some years ago, I rode my 10ah bike back and fore along the seafront. Obviously it the path was completely flat and although there was a light wind, going in both directions evened things out. I did not pedal at all and got about 14 miles before the battery ran out.

No the computer is continuously calculating your power consumption and your current milage and is estimating that at current consumption what your range would be. This is very similar to the range calculation in a modern car where after travelling a number of miles your estimated range can increase...
May 8, 20178 yr With a 2752Wh battery Funny you should mention that, I am looking at a 50 Ah battery for my new project. Should get me about 300 km range...
May 8, 20178 yr Funny you should mention that, I am looking at a 50 Ah battery for my new project. Should get me about 300 km range... Tell us more.... I should be getting that sort of milage, but I'm too much of a power whore. When I'm really hooning around, I struggle to reach 40 miles.
May 8, 20178 yr I've done about 50 miles on my new bike so far. I'm hoping to go through the whole summer without charging it. The battery hasn't gone down at all yet.

June 7, 20178 yr i have a city bike with 250w bafang motor and waterbottle shape battery. it is 10.4 ah. it is current conttrolled and can deliver very low assist power when programmed. i have nexus 7. Me and 2.5 year old kid, spending time and doing very slow trips, when i pedal normally and use only first or second gear with a normal cadance, even there are so many hills to climb around, i usually get 45 to 55 km which is approx 34 miles. if i am alone on trips, this would be 10% more. if it is a flat land, that seems possible to reach 50 miles.
June 7, 20178 yr 88miles on a journey to and back from on the S/Downs last week. Extra Ah carried in panniers, off road uses far more Wh then road riding.
June 8, 20178 yr I'm up to about 200 miles on my new bike now, and I still haven't charged it. When will you be unloading it from the car?
June 8, 20178 yr When will you be unloading it from the car? I think he's doing it the sneaky way, plugging himself in for a full charge of carbs, proteins etc. There's more than one way to tackle hills, Lance Armstrong got very creative in that direction. .
