Re: Interesting videos for trike owners

Welcome to the Dark Side, Roger. I hope you enjoy the experience. You're right that a trike allows you to jump on and ride without the period of becoming competent in handling a 2 wheeled 'bent. But, even so, it's still a quite different experience to an upright. And I don't just mean solely in the ...

Re: Crank speed/power output relationship .... questions.

.............. The better ebike kits have lcd with five pas levels(cadence pedal assist sensor) and intelligent controllers, cheaper kits have basic controllers and pas systems usually 1 or 3 speed functions so none or very limited power control under pas. Thanks for the reply, hemo. Very informati...

Crank speed/power output relationship .... questions.

As a complete novice to electric assists I embarked on a conversion project. I bought a new (but cheap on eBay) front hub motor, and associated wiring. I built it into a rim I already had. I found a suitable battery, also on eBay. It works fine. I have two modes - twist throttle or pedelec. The thro...

Re: Sturmey CS RK-3 stripdown - a query - now solved

25miles this morning on the Moulton. Out very early because it's going to be a scorcher today. Not ridden Moulton for over a week, so any of the soft grease that would have settled, must have done. After and during the ride, there was no leakage seen. Also, I was riding in near silence. SA hub was ...

Re: Roller Pinion + Shaft Drive

The bicycle as a basic design of which we have now, was invented a century ago. They still haven't improved that design despite many many ideas. This is just yet another dead end IMHO. I saw this report at the beginning of the week, and felt it was a solution looking for a problem. But, nonetheless...

Re: Sturmey CS RK-3 stripdown - a query - now solved

Good morning guys.......................... One issue that I found last time I had it in bits and this time too, is that the pawls on the LH end - forgive me but I'm not sure which ones they are technically - but they're the ones that engage on the inside of the hub shell - don't seem to have a ver...

Re: Sturmey CS RK-3 stripdown - a query - now solved

............. I note also that (IIRC) the individual spare parts appear not to be available for this hub, so barring the (few) parts that are used in other SA hubs, if you encounter a problem a whole new centre is the only solution. cheers I'm finding this thread (and the one alluded to in which Mi...

Re: Sturmey CS RK-3 stripdown - a query - now solved

The ring has shifted, using a punch. The secret was to apply a larger hammer ( thanks for the tip, Mick). A couple of strikes, even without much input from me, did the trick. Thanks for the help everybody. Onwards I go into the depths of an internal hub, as a complete virgin (no funny moments, pleas...

Re: Sturmey CS RK-3 stripdown - a query

Thanks for the advice so far. Most informative. I've had a preliminary attempt with a mild steel punch. It seems not to damage the hardened steel casing. But, it hasn't shifted. Maybe I don't have the confidence to give a sharp enough blow. Like Mick, I'm a little "offended" to apply this ...

Sturmey CS RK-3 stripdown - a query - now solved

Hi, I'm stripping a Sturmey Archer CS RK-3 hub. I've never stripped an internal hub before, let alone this particular model. I have a query and I can't find answer on the internet. I'm at the point of screwing out the planetary gear assembly from the hub body. On the internet (but applied only to ot...
