The waiver was April 2013, more recent than Norman's tenure of course. .

Agreed Martin, that 40 Nm is frightening, and some have sheared the bolts. The bolt quality seems to have been variable too, with a few cases of the threads stripping. That's why I duck out by just saying the bolts need to very tight!

And no doubt you won't Phil, this issue has been embarrassing for the DfT since 2003. Of course your contact with Norman Baker was well before the issue of the DfT waiver permitting 250 watts on e-bikes, pending legislative changes making that permanent. .

And at Bristol there's Atmosphere Electric Bikes with a range of 13 brand names, so well worth a trip there. Quality and reliability has leapt ahead for most makes, and for most brands the service given by suppliers is now quite good and often excellent. Where over six years ago poor service...

It's another case of not enough cyclists, notice here were no others in sight on that road. When they are few and far between drivers tend to fall into the habit of only looking for other motor vehicles and completely miss seeing a cyclist when they glance ahead before looking and turning...

You'll find the latest generations of these crank drive bikes to be appreciably more powerful than your Agattu, and they don't phase down the power so early either. Full power is available all the way to the assist limit. And hub motor e-bikes have come a long way since 2008 too. Some of them...

Like d8veh I thoght the number of cars sticking out were worrying, they would have made me very nervous about their possible intentions. I'm guessing that road has such a high traffic frequency that drivers start to get impatient waiting to get out of side roads so start pushing out further. .

I doubt one would have much worthwhile pawn value after use, the recovery cost would be quite high with cleansing stages before smelting. .

I think he's just guessing. ;) .

Welcome back Musicbooks, it's good to hear from you again after such a long absence from the forum. I'm glad your Agattu has lived up to it's early promise, they have proved to be one of the most reliable e-bikes ever. .

On a legal techicality that's true since our UK e-bike law still is limited to 200 watts, However a DfT waiver extends that to 250 watts rating. Above that the Low Powered Moped class applies to machines up to 1000 watts with or without pedals or throttles and still limited to 16 mph motor...

Moderate price silver finish chains like this one which are often nickel plated I've found to be rust resistant. I daresay Rohloff's 24 carat gold plated one at £125 is too. :rolleyes: .

I've received a link to Martin's review article on this new Yamaha unit which you may like to read. It's on this link .

It's not quite as new as it might seem. The Impulse unit was developed by Kalkhoff from the German Daum unit which was on the market before the Bosch one. Of course it has been upgraded with modifications in both Impulse stages so each change will have been around for a shorter period, but at...

Yes indeed Richard, I meant the motor unit. Here's a photo of an upside down frame showing the three bolt holes for the motor unit arrowed. Your frame shape is different but the hole relationship is the same: And here it is with the motor unit lined up:

It could be a crank arm slightly loose on the square taper of the pedalshaft, but on these it's most likely to be slackness in the three large bolts that secure the unit to the frame. The frame is painted and over time the strain of applied pedal force works the faces a bit slack. You'll need...

Of the three e-bikes I owned together at one time, the 26" and 28" wheel ones I no longer have and the 20" wheel one does it all brilliantly and I don't feel deprived. But of course I am a pensioner! .

You can read about it on this BikeEurope link .

That type could either drive the rack with a cog, a bit like the Heinzmann etc but with the motor bulging externally, or use a chain from a motor sprocket to a larger sprocket, a bit like the old Cyclemaster petrol bike motor hub drive. The last one I ever saw like this was imported by F2...

It sometimes seems that way, but it's not with everything. We are the world champions of low cost services. For example, the low cost airlines we invented or helped to flourish, Freddie Laker years ago and today's Easy Jet and Ryanair. Note the Easyjet founder was Greek, but came to England...
