Hello Andy I'll have a look (and test) my one tonight. I've been busy over the last few days so I haven't put it on the bike yet. It looks exactly the same as my existing one so I don't expect any problems. I'll post the results later.

I've just purchased one of these controllers from e-crazyman. The controller arrived on Friday about one week after the order (not bad from Hong-Kong). It's exactly the same as my existing controller as I hoped, so now I have a spare in case of failure. I haven't tested it yet though. The...

I've just seen my local powabyke rider pushing his bike along the pavement. Looks like his battery may be giving less range in the cold weather. :( Poor bloke, that's not a bike I'd like to push. He must have had a minimum 2 miles to go as well. :mad:

I agree with that. Some years ago me and the wife were riding off-road in winter on a compacted mud track. Suddenly we rode onto a large patch of sheet ice which had formed on the track. The wheels slipped immediately and violently but luckily we threw our legs out quickly and kept...

Great, I hope it fits your needs. I didn't find it though, I saw it on endless sphere: Endless-sphere.com :: View topic - Affordable 48v brushless controllers, such a beast exist? ? Paul

It may well work and for only £20 you can't go wrong. 48V might be a bit scary though. I get 24mph on the flat at 36V with gentle pedaling, at 48V I might get 32mph. :eek: The controller looks to have a speed control pot (blue wire) which you can turn to adjust the speed of the wheel. I...

Hello all I've just bought one of these on ebay: Item # 300166787182 It seems to be the same as my existing controller so it'll be great to have a backup. Only £20 as well! There are other ebike parts available if anyone is interested. Paul

Hello Francis These two threads may be of interest. http://www.pedelecs.co.uk/forum/electric-bicycles/199-measuring-your-hills-percentage-figure.html?highlight=hill+percentage...

I got 16 miles out of my 36V 9Ah Ezee Nimh this morning (avg speed 18.6mph). Temperature was fairly mild 8 to 9C though. Tomorrow morning looks to be down to 3C, brrr!

One rule of thumb is to stand astride of the top tube and ensure there is an inch or two of clearance between vital parts of your anatomy and the tube. ;) The only way to know is to try the bike since there doesn't seem to be much consistancy in frame measurements between different types of...

I totally agree flecc. We see this everywhere from the Health and Safety brigade. Using their methods I dare say that several thousand deaths or serious injuries occur whilst doing almost anything. I think they bandy these stats around when they know they haven't got a case.

Who killed the electric bike? Are the oil companies behind this?

I've got two rear lights, one on the seatpost and one on my backpack (though the clip has snapped so I've cable tied it to the bike for now), one flashing and one fixed. I also have a home-made 12V halogen MR11 mounted inside a plastic plumbing pipe reducer running off a 12V SLA. This is...

The thing about falling off your bike is that most injuries tend to be to the arms and hands as you instinctively put your arms out to protect you. I don't believe the head actually takes the brunt of most cycle accidents. Here is an interesting link to cycle helmet related research...

Have you tried the usual unplugging it reconnecting it? My powacycle Nimh charger did something similar some months back and I just disconnected everything and reconnected 1/2 hour later and all was fine.

I slipped on some wet mud whilst exiting the 'dangerous' road turning right onto a 'safe' cycle path last week and was thrown off the left side of my bike when the front tyre rapidly and violently regained traction. I hit the nice soft grass with my left shoulder and the momentum rolled me all...

I've found another source for step down regulators...

I suggested the section on user experiences with their batteries so that it would jump out at visitors to the site without the need to trawl through posts to find them. Having said that you wouldn't have to look hard to find opinions on the batteries. My main concern is to clearly get...

Hear, hear. I still have a 24V li-ion but don't use it for biking. I am looking to use it to power my home-made bike lights. I just need a 24V (well 28.4V) to 12V step down convertor thing and I'll be in business. :) At the moment I use a 12V SLA for testing purposes. I think we need a...

Hello there It could be that the spokes were not tensioned correctly and thus the wheel quickly went out of true. You may also have spokes that are not strong enough for the job. Here is a link to further information on spokes: Building Bicycle Wheels by Sheldon Brown
