I've only just noticed this thread, or otherwise I could have jumped in earlier. My Quando sounded like it was firing on three cylinders, particulalry at low speed. While looking for the fault I removed the handlebar unit with the three LEDs (the voltage indicator). When I did this I...

20 inch wheels I bought a Brompton and loved the Swiss watch engineering and innovative folding method. I did a few hundred miles on it, but after the novelty wore off it was pushed to the back of the garage and never used. I never enjoyed the ride, and I think the small wheels were mostly to...

Potholes Yes, some of the roads I use in Leicester are getting to be very pitted recently. Where the roads have been patched the surface still has ridges and hollows. A supspension seatpost takes out some of the shocks but it can be very unpleasant if you don't examine every metre of road...

It has always been a problem with folding bikes that the wheels cannot be folded. Here is an interesting proposal to get over this difficulty. duncfitz- Crossbreed folding wheel The tyres remain inflated when the wheel is folded. Lets hope that this leads the design of folding bikes...

Sprint motor Flecc, Yes that big heavy steel item would be relatively expensive. It seems to have no other support apart from the sprag clutch/bearing unit, which also has to be big, heavy and expensive. The SB arrangment probably saves weight and has cost benefits at the expense of a little...

Sprint motor Flecc, No, have a look at the picture below. The orbital gears engage in the black coloured ring gear. What isn't obvious from photos is that the ring gear is not fixed inside the hub. It can rotate relative to the wheel (in one direction at least). The black coloured ring gear...

Sprint motor Flecc, For interest, when I stripped down the "Sprint" motor on my Chopper I noticed that the freewheel was between the gears and the wheel. I must try to do some freewheel comparisons between the Chopper and the Bafang-motored Quando. Peter

Good idea This is an initiative of which I definately approve. I will try to support with suitable photos.

Antique radio gear Mussels I now have a picture in my mind of you carrying a load of battleship-grade radio equipment and several big black Avos. Mussels or Muscles? Torrent99 Is Birketts really still operating? It's worth a trip to Lincoln to have a dose of nostalgia. The near-equivalent...

Early test results I'm still short of time to do some proper testing, but I managed to lash together a 20 ohm load from wirewound resistors and the results are as follows. This is using a NiMh 36 volt battery as the power source. Maplin Meter/ Old digital Avo Reading 39.6v / 39.9v...

I'm with experimentalists Well, I've bought a Maplins meter and done the conversion. I've not had time to test it on current yet, but I can confirm that it does say DC when you put a DC voltage across the wires. I understand that its not for everyone, but I love this kind of project...

Maplins Meter Torrent99, Thanks for letting me know about the posibilities with the Maplin power meter. Are you referring to the Maplin L61AQ item? Plug-In Mains Power and Energy Monitor > Maplin I might just have to point the bike towards Maplins tomorrow. Looks like its going to be a...

Re-celling Bert, As far as I'm aware it is not really possible to re-cell a Lithium Ion battery. Each cell has an electronic circuit called a battery managment system connected to it, actually inside the battery casing. The whole thing is just too complex to replace as a do-it-yourself project...

Risks I've been thinking through the risks associated with taking up to 20 amps out through the fuseholder. It seems to me that the biggest risk I'm running is that there will be a bad connection where I've shown the red spark in the picture. There is a risk that a spark at this point...

Flecc Flecc, Thanks for the offer. I'll send a PM. Sector (Pete)

Maplins Ammeter Maplins Item N48Cy is a "Car Current Tester". Automotive Current Tester > Maplin It is intended to be connected in place of a car-type fuse as a check of which circuits are using current. This, of course, was what my battery fuseholder modification was trying to do for round...

I wanted to measure the current consumption on my bikes, but didn't want to disturb the wiring between the battery and the motor. I thought I might do it by removing the fuse and replacing it with an adpater that would bring two wires out for the current measurent. I took the fuseholder cap from...

Plug for Bob Warner Cycles Leicester Here is an opportunity to recommend Bob Warner Cycles in Sparkenhoe Street, Leicester. Bob is well known locally for specialising in spoked wheels. He didn't flinch at all when I took in a 20in E-Bike back wheel with short spokes and a Nexus hub gear. He...

The old 50cycles web page on the Ezee Chopper said that they were for people 5ft 6in or less. 50cycles Advanced Electric Bikes - eZee Chopper electric bicycle specification and reviews I'm 6ft 1 in and feel fairly comfortable on the Chopper, although it has to be accepted that the geometry...

Nickname I understand that the nickname "Organ doner" has been adopted for this type of courier cyclist.
