I have an Ezee rear motor, laced in a 26” rim, that’s been hanging in my garage for the last three years waiting for me to do something with it. If you’d be interested in it let me know and I’ll send you some details/photos.

Another option is to try walk mode by pressing and holding the down button. Motor should then rotate slowly if it’s working.

Have a look at this guy’s website and YouTube channel. He knows what he’s talking about and his reviews appear to be unbiased. https://www.mobile-solarpower.com/ https://www.youtube.com/user/errolprowse/videos

One more thing you could try. There is a possibility that your controller is configured to meet the EU standards so that the throttle will only work when the pas is engaged. If your 810 display has a 6kph ‘walk’ button, with the motor reconnected and power switched on, try holding this down and see if the motor turns. If the motor moves with this, but not the throttle, it’s most likely a controller configuration or throttle problem. If it doesn’t work you’re back where you started as this button may not be configured either.

What’s wrong with the Schwalbe AV/SV21F? https://www.sjscycles.co.uk/inner-tubes/schwalbe-av21f-fr-schrader-tube-275-tyres-54584-to-75584/ https://www.sjscycles.co.uk/inner-tubes/schwalbe-sv21f-fr-presta-tube-275-tyres-54584-to-75584/ I think they both have a removable valve core but you could always contact Schwalbe or SJS and check.

Most hub motors are designed to fit frames with drop-outs, so won’t fit a bike with the newer through axles, at least without heavy modification. I believe there are now motors available to fit these through axles, but I’ve no idea where to get them. Perhaps someone else can help. http://www.bike-eu.com/sales-trends/nieuws/2017/08/bafang-hub-motor-for-e-mtb-and-speed-e-bikes-10131126 A crank drive conversion will probably be easier.

Is this the bike you are talking about? http://www.halfords.com/cycling/bikes/mountain-bikes/boardman-mountain-bike-pro-full-suspension-27-5-16-18-19-20-frames The website spec. for this bike claims it has a 12x142mm Bolt Through axle. If this is so it might cause you problems trying to fit a normal rear hub motor.

I think they fit direct drive motors as it permits a reverse gear. If you don’t need reverse drive a geared motor, as mentioned above, would be fine.

Excellent. I often buy those Duracell Industrial so will be interested in your findings.

The Consumers Association have tested various AA and AAA batteries and published fairly comprehensive reports in their Which magazine. You can read them online if you sign up but most libraries around here seem to keep copies in the reference section, which is where I read them. The latest report for AA size was in the December 2017 edition. AA and AAA sizes are in the December 2016 edition. Their ‘Best Buys’ ignored price so tended to favour the more expensive ones, which generally lasted a little longer, particularly with high drain devices. However, what I found most interesting was the ‘Cost per hour’. For medium drain devices this was 14p for the AAA Energizer Ultimate Lithium @ £1.75 per battery compared to only 1p for the Wilko Extra Long Life @ 12p per battery. So although the Wilko was the worst performing, lasting 2/3 the time of the Energizer, it was 14x cheaper. Going back to the original question, and going by the CA test results, I would expect the Lithium ones to possibly last a little longer, like for like, but those Duracell alkaline ones to be much cheaper overall. Why not buy some and compare them yourself?

There’s also the newer Heinzmann DD motor kits. I believe available from a few UK dealers, but rather pricey. http://www.kinetics-online.co.uk/electric-bikes/heinzmann-electric-bike-kits/

If, like most folders, this will be a one size fits all frame you need to offer as much adjustment for fit as possible. On the Birdy R&M offer a choice two angles plus adjustable height for the stem (handlepost), Brompton offer a choice of handlebars with different heights, and many cheaper folders have a telescopic stem. At the least you need to offer a telescopic stem option. It may add weight, cost, and arguably spoil the aesthetic, but would make it a better fit for a much larger range of customer.

Mine’s fine, but then I don’t see any ads. Try this: https://adblockplus.org/

Have you set C1 correctly? C1=6 works for me but 5 or 7 should also work according to the manual.

Nope, battery voltage was around 36.3V offload, 36V while testing.
