Redshift ShockStop Suspension Stem for me superb bit of kit.

Take a look at Cytronex.com for an alternative method which may suit your frame.

I would not risk using a 750 watt motor on those dropouts, you would be relying on the wheel nut taking the full torque of the motor. The surly items are for using the dropouts with a fixed wheel. You would have to rely on the small thumb screw adjuster to hold the axle in place. To me it just...

I have an almost new silver Swift awaiting a very light conversion to come on the market. Still looking. There was a e swift for sale recently ,a one off conversion with a custom battery shaped to fit between the seat tube and back wheel .Very neat job but never came on the market. Brilliant...

Ask on pedelecs.co .uk, most bike shops will not look at these and ebike shops will only service their own brands. You will need to find a fellow ebiker with the skills required.

Keep in mind what happened to Michael Schumacher, when he hit the snow with a helmet camera. These things can do serious damage to your helmet and skull if you come off .

That is a known good seller in the UK. The battery is a good one. One thing to check, are your rear dropouts vertical. This is essential as if they are the older slanted type the motor power will pull the wheel out of line easily. Your frame looks to be large enough to retain the downtube...

No drive- Check if the chainwheel threads are stripped, the drive shaft will run but the chain wheel will remain stopped. The drive is transferred to the chainwheel via the thread only. If your threads are stripped inspect the drive shaft for a hairline crack across the thread. This will...

How do you intend to stop this 200 kg projectile at 60kph ? Should be fun on wet London roads on a botched up frame and bike tyres.

The Bewo gear case is very sparse on grease from the Factory. Your problem is possibly this. There is a sprag clutch which engages as soon as you pedal and this may be dry. The gear case really needs to be opened and well packed with a good lithium grease. I have sent you some info on the chain...

PM sent.

Been running mine 14 months now, 48v @15amps, (max amps can be set from the panel), no problems. Dismantled and greased once, I made the tool to remove the chainwheel. Otherwise regular tools. The motor shaft is supported at it's outer end in a needle roller bearing located in the outer case...

Update for anyone interested. The battery was returned with a completely new Samsung 29e cell pack and BMS at no cost to me. I can only conclude that the original was of unsatisfactory quality . I would deal with this supplier again without hesitation as they stand by their products and honour...

Thanks for your response, I reckon you are right. The battery has been sent to Insat in London uk for test & repair as required so I have no recent voltage readings. I do recall that it was down a bit being just over 50v. I will post the result as it may be of help. The other bikes are OK so...

Any comments on this welcome, I have 4 bikes and run them on a turbo trainer to hopefully keep the batteries in condition. I always run at a medium power setting/middle gear on CD bike, 12/15 mph on panel and nothing gets even slightly warm. I let them run down on throttle till half the bars...
