if you have got a multi meter you can calculate as per thread https://www.pedelecs.co.uk/forum/threads/how-do-i-calculate-watts-used-per-mile.31067/

I used the old fashioned way, after riding over hawthorn cuttings. Tyre liners then cut the old inner tube lengthways & slip over the new tube. 4 years with no more punctures. With my replacement bike I fitted Marathon Plus from new.

if its only a 20 mile round trip - that's 10 miles each way. A maximum speed of 20mph will get you there with only a few minutes difference, as your average speed is likely to be very similar. Its your maximum speed that provides the potential for the greatest danger. At 20mph any ebike's...

No - I sent video to Police because I was going faster than 10mph, hence the vehicles overtaking were breaking the law. Even when I was using a 250w rear hub going up a 10% hill I exceeded 10mph. When cars see a cycle the majority want to overtake asap, even when its not safe to do so. I got the...

why do you think I am riding slowly!

Even video is not good enough - I use the A2, which in parts is very narrow, goes up blind hump backed hills with solid white lines. When cycling I am in the nearside wheel-rut (which is kept clear of debris) but means that if a vehicle wants to over take they have to cross the central solid...

evening can you please post me in ME9 (Newington) as several villages within same postcode area

"You need a Watt meter between the battery and the controller, it will give you all the information you need about your battery usage. That is how I know I average 5.8 Wh/km - return trip to my GF's house is exactly 9 km and the watt meter reading is 53 Wh used. You also get peak Amps and peak...

I have only seen pictures of those Laser lights, and did not know if they would work over a rear pannier. What is your experience with them?

This was taken at 50m, showing wilkinsons high intensity led at top, with a normal bike led underneath and my experimental LED strip lights. When I have followed other cycles I thought that its the size not brightness that draws the eye. So using 5V flashing LEDs I mounted them onto my rear...

I understood & followed everything but would just like to check something Percentage used is based upon 36v battery (18650 x 10 cells) so max voltage is 4.2v x 10 cells = 42v so min voltage is 3.2v x 10 cells = 32v so difference is 10v hence in your example start volts less end volts divided by...

I know the voltage before & after ride & mileage is this sufficient information? I have a 52v 17.5Ah battery. 100% = 58.8v 0% = 42v so 16.8v range. if I start at 55.5v (55.5v-42v/16.8v = 80%) & use say 15% of the battery to cover 15 miles I can compare different assist levels But without...

Thanks for the informed & some witty replies. My proposal does not stand. But my objectives remain. What legislative changes will provide for safer road cyclists. What will get car COMMUTERS to move to ebikes?

The triangle at the front to warn vehicles waiting to turn in front that its faster than a normal bike, the rear triangle to improve its visibility. I have always assumed that the government would impose additional restrictions - helmets, insurance etc the same as Germany did for s-pedelecs

What I would wish is an ebike able to keep up with urban traffic. At present for lots of the country that means 30mph, but without other changes that would be dangerous. 1- change legislation to protect cyclists - see previous posts 2-change visual impact to differentiate fast ebikes - see...

Without a change to protect vulnerable road users, it only ever be a minority who will be prepared to ride in traffic

Lovely looking but as it does not look like a moped car drivers will treat it like a bike https://www.sciencedirect.com/science/article/pii/S1369847815000662

I agree that the best solution would be separating cars from bikes & reducing to 20mph but I do not believe that the cash is available, so I thought of an alternative that could be implemented now with no cost to government.

If that happened - bedlam - but as per my webpage what I proposed was that fast ebikes must be visually different from cycles. I would suggest an upsides down flashing illuminated warning triangle the width of the bike - front & back. Also fast ebike would be limited to roads, as any vehicles...
