Comparing 36v 250w to 500w Hub Motors

To give you very rough idea of the area of panel required, each of the small flexible panels on my array is nominally 12 volts (no load) and 2.68 watts. Under load they were rated at about 8 volts. Allowing for losses etc, I reckoned they were putting out about 2 watts each. So imagine 100 of those ...

Comparing 36v 250w to 500w Hub Motors

I was also wondering how much a panel like that would set me back? If you live in Perth here's a nice place to go. https://www.12volt.com.au/redirect.html?a=/General%20Htmls/webcat2003/solarpage.html You can get some prices there. My first portable set up I had the "V" shape to try and minimise wid...

Comparing 36v 250w to 500w Hub Motors

One of the mods I had done to the green trike was to have a torque stay anchor welded to the rear fork. Prior to that time I'd simply used a metal hose clamp around the torque stay and the fork, wrapped in rubber padding and duct tape to stop scratching the paint. This lasted for several years with ...

Comparing 36v 250w to 500w Hub Motors

I wonder if a mirror/lense system may work which may allow you to run an Octoganal shape tube with solar panels on the inside? Silly idea I know (not very well thought out). At least there wouldn't be any particular reflection unless you looked at it from the sky . Whilst it won't be portable in th...

Wow thats very impressive. How powerful are those solar panels? I'm hoping to score one of those trailers similar to yours, but i'd want to convert it so I could mount it to the back of the seat.

Faz, you seem to be missing several points. Firstly, you seem to think arguing the matter with me will achieve something. Even if you do convince me (of anything), what good will it do you?

   It would never have worked with 500+ watts, simply because it would have flattened the batteries too quickly for the solar panels to recharge adequately. Ah the bike only consumes what it needs to. If you use 200W going 20kph you still only use 200W with a 500W motor at 20kph. Ah, Who's going to...

Like comparing apples to oranges. I can't see electric motorcycles taking any customers from the ebike market. That's exactly the point. It IS apples and oranges. As proposed in the legislation, there will be a limit of 250 watts, which is really only an "electric assist" function. If a rider wishe...

The slopes are given as an incline ratio. For example 1:.1 would be a slope which rises .1M for each 1M traveled horizontally. In terms of % a 1:.05 is a 5% slope   a 1:.2 slope is 20% slope. An approximate conversion to degrees is %slope ~= Degrees i.e. 1:.05 is around 5 degrees. i.e. 1:.25 is aro...
