Roughly yes. The rear sprocket on the Agattu 7 speed was sometimes 22 tooth so little different, but the chainwheel was always 37 tooth and motor sprocket 9 tooth as standard. Either an 18 or 19 tooth rear sprocket would be ok, as you know the power phase down on the Agattu is such that it's...

I don't know that one, but there was a flush of Chinese motors on these lines in the 2003 to 2005 period, mostly on cheap e-bikes in the £300 to £450 bracket at that time. Raleigh UK had a variety of attempts to introduce e-bikes, all very short lived until they adopted the Derby Cycles...

Of course such publicity always presents in the best light, but being familiar with Yamaha's past e-bike motors and bikes I've little doubt that it will be good. They wouldn't enter the market against a company like Bosch unless they had a good chance of success. When a German company like...

Given how sound the original Yamaha motor units were from 1999 on, plus their major position in the Japanese market, I'm quietly confident that this new design could be rather special. It has the high efficiency of the single stage reduction that the current Panasonic units have, but with the...

Hi Hoppy. Tom was concerned about the introduction of motor vehicle like bureaucratic measures on legal pedelecs. Since we have accepted the EU motor vehicle type approval legislation which doesn't permit a later introduction of something which matches the EU pedelec specification, that can't...

Martin at e-bikeshop has passed an article to me with further information on this motor which I thought you might appreciate seeing. Here's the link .

Here's another very precise comparison. I've owned two e-bikes of the same make with identical motor, controller and batteries. One has the hub motor in a 28" wheel. It assists to 22 mph but is a useless hill climber unassisted, on power only quickly stalling on a 7% slope after a flying...

You can differ as much as you like Hoppy, any lawyer will know how wrong you are in law. Once again you've distorted the position by stating that law defines pedelecs as bicycles when I've specifically said it does not do that. Here's the relevant sentence from my earlier post: "2002/EC/24...

There's some information in this thread about derestricting Wisper 905 models. In particular post 19 on page one may help.

My TomTom once did a similar thing in Dorset, taking me off the main A road onto a narrow lane route that brought me back on the A road over a couple of miles further back than I'd been before. .

Yes, very simple. Just change the rear hub sprocket for a smaller one. The smallest at 16 tooth gives assist to 20 mph, but that's going a bit too far for the limited power and also slashes the range to as low as 18 miles on a new 10Ah battery. The standard sprocket is a 23 tooth so reducing...

You're in on page 2 Rob, riding on Whiphill Lane: Map Link .

When the handlebar stem is folded, is there an Allen bolt head beneath that can be tightened to adjust out the slack? The photo below is of a similar folding stem showing the Allen bolt in the centre of the lower half and centre of the photo that tightens the bearings:

No Hoppy, we can't extrapolate like that. 2002/EC/24 lays down what are two and three wheel motor vehicles. It merely excludes pedelecs from that motor vehicle law, it doesn't define them in UK law. In UK law an EAPC as we legally call them is defined by the 1980s laws I've already quoted...

Yes, typical old cycling offences are Drunken cycling, Drunk in charge of a bicycle which applies even when dismounted and pushing it along, and Furious cycling. In addition there are some public order offences which can be applied. A driving licence cannot be affected by a drunken cycling...

Only in one way. 2002/EC/24 lays down the rules for type approval of two and three wheel motor vehicles. Article 1.1(h) is one of the seven listed exemptions from motor vehicle type approval and it specifically excludes pedelecs conforming to EU law on those machines, regarding them as...

I think the crucial difference was more to do with the sheer scale of cycling in those countries rather than just the presence of representations. With some 70% of the Netherlands population riding bicycles regularly, no government there dares to upset cyclists. We of course have a dual...

They do in the sense that they climb better for example. That's due to the mechanical advantage of the smaller wheel, and it applies whether an electric assist or a pedal only bicycle. Offsetting that advantage is less stable handling and steering. .

Well done Mary, and thank you for the information which is valuable to the many other Giant Lafree owners. .

They say they have some second hand from £500 Phil, so there just might be something.
