Power and battery ?

[BusyBuilder]

Looking at various bikes, I need one for swmbo, they all have different batteries and power, like 36v 10amp etc.

I'm lost as to what to get, bit of forest track and down to shops, so probably a hybrid.

And less than £1000 if possible ?

Have a look at the haibike trekking range, you'll probably be able to pick 2 up for just over £3k

Bit of trail and shops.....chinese bike.
36v 10ah will give 20/25 mile range.
My mate just got one from Argos... £700.
Only has an 8.8ah battery though so ignore their claim to 35mile range.

'Your mileage may vary' ..... literally!

The distance your ebike will go depends on your battery size and power usage. The power usage you can set by the choice of assistance level but, much more importantly, your weight. The heavier you are the more battery power it takes to move you.

Both our bikes have the same wattage motors but my wifes has a 13amp/h battery and mine has a 15amp/h battery. She weighs half what I do and thus her bike will go farther on one charge.

As an example today I was riding on a disused railway line (Cheshire Lines NCN62). In power level 1 I was using about 60watts to do 13mph.
Coming back the gale was blowing in my face and I moved up to level 4. I was now using 250watts to do 13mph.

At that rate a 15amp/h battery @ 36v is 540 watt/h, using 60watts should last 9 hours. At 13mph that's about 117 miles!
Or the same 540 watt/h battery using 250watts should only last 2.16 hours or 28 miles.

All the above figures ignore friction losses and the fact that you can't use all 540watts from the battery etc but gives you an idea. In the real world I have cycled 25miles in a day and used half a battery. That was a mixture of flat and hills on a hybrid Cube bike.

I hope the above helps a little bit ....

ps. Converted my own bike with a kit for lots less than £1000.

Tried E.Bike at Halfords earlier in the year, not that impressed so we have carried on using pedal power..Not really struggled any where in Spain yet this trip.Mind you we do avoid mountains..May try a few e.bikes out this winter..BUSBY.

Can I ask the name of the kit as I fancy doing mine.
Cheers.

It was a 'Season' kit from eBay seller Yosepower. Looks like he is not trading at the moment but there are lots of other kits to choose from.

 

[Neil Bedwin]

Update.....

This is basically the same kit as I fitted.....

Looks like Yosepower-uk has rebranded the kits to have his name on them!

We each have a E-Ranger bike, who display at the shows cost us about £900 each 2 years ago when we bought them we can do between 25 and 35 miles depending on the terrain on the supplied battery, very pleased with the cost, equipment, and range ratio.

I'll second what Steve N Tracy said - E-Rangers are great - we've had two for a few years. They're well made & comfortable too.
