    Both my e-bikes stolen

    She's of the opinion any passer-by could have spotted them at any time the garage door was open, blaming me for doing so whilst giving the bikes a wash recently. The place is on a fairly busy thoroughfare My opinion is it must have been a van job. The odd thing is, I'm up very late, she gets up...

    Both my e-bikes stolen

    They were nicked from the garage attached to the house I'm currently living in. It's my girlfriend's house, I'd be astonished if it's anything to do with her. She has had the builders in recently. It's NW London, borders Wembley and Kingsbury. She thinks it's professionals. I don't, they left...

    Both my e-bikes stolen

    Went into the garage of the place I'm staying at the moment and to my horror - both bikes gone, stolen sometime between Wednesday evening (26th) and this afternoon. 1. Brompton M6R with Nano conversion. 2010 model. Black with red forks and rear triangle. Cateye Velo computer. Integrated lights...

    Nano Brompton - Bosch battery not charging. What to do?

    Thanks to vfr400 for such a prompt response. Had an inkling a duff cell might be the case and your diagnosis confirms this I think. Taking the battery apart and certainly welding in new cells is way beyond me but you've helped clarify for me what to do. Once again, my thanks.

    Nano Brompton - Bosch battery not charging. What to do?

    My Brommie was converted just over 3 years ago. Still on the original Bosch 4 amp-hr battery, though had to get a new charger in January after the original died. All went well till last week. I'd run the battery down to the flashing red light level. Putting it on the charger, that also gave a...

    Brompton conversion... would this Whoosh kit work?

    Checked with Nano's today and they confirmed they do still use the Tongxin motor, whilst adding that it has been improved over the years. As it's not a Bafang as previously discussed, I would still wonder at the wisdom of "hotting it up" though..

    Brompton conversion... would this Whoosh kit work?

    I thought the Nano kit used the Tongxin Nano motor, which a search on this site gives the advice they don't take kindly to extra current or over volting. Does anyone know when (or if?) they changed to the Bafang?

    Brompton conversion... would this Whoosh kit work?

    Interesting Woosh's reply to my post seems to be gone today. My reply to it would be it's fine if you want a small bag for a Tablet or knick knacks, but my suggestion leaves you free to use any bag Brompton or others provide, just as on a standard Brommie. To answer DBrown67's post, if you look...

    Brompton conversion... would this Whoosh kit work?

    Well, the electrifying Bromptons market seems to be hotting up. We've had Nano for years, now there's Swytch with Woosh in hot pursuit. If Swytch's prices double after this Friday then no doubt Woosh's kit will give them a run for their money. I own a Nano Brompton and a delightful thing it is...

    The development of the brand new 2020 Wispers... in Pictures!

    Was the centre drive version of this the bike the one that was touted a year or so ago as possibly having the option of having a hub gear? IIRC the new version of the Sturmey 5, which is advertised as being suitable for e-bikes, was mentioned. If so, why was the idea dropped in favour of...

    Attaching lighting set to main battery on a Big Bear

    Thank you to all for your contributions in answering my original post. Whilst I appreciate attaching self contained battery lights is an easy answer, I've never had a happy history with these things, going back to the days of 'Never Ready'! I regard them as a lash-it-on-afterthought. Cars and...

    Attaching lighting set to main battery on a Big Bear

    Got a second hand Woosh Big Bear through these columns a couple of years ago. Rode it round for a bit and great fun it was too. After a few repairs were needed anyway, decided to take it off the road in order to turn it into a more practical machine for me. All of that (north road bars, frame...

    IGH gears vs. derailleur

    If Woosh do end up doing a Kreiger/Bali/Big Bear (Front hub motor is ok with IGH of course) with a decent hub gear (Shimano 8? Sturmey 5??), reckon I'd be on the next train to Southend :) As an aside, it baffles me why no-one ever uses 3/16" chain for CD bikes with a hub gear. It would surely...

    Brexit speed question.

    I can see that an 'S' class, with machines capable of nearly 30mph would have to have extra restrictions, as otherwise the Motorcycle trade would doubtless loudly cry "foul"! I also accept that the OP's suggestion of legalising power up to 20mph or so is most unlikely to be adopted. What I...

    Big bear for charity

    I went down to Newquay by train on Saturday and bought wolfmandave15's (lovely chap) Big Bear - the deal being done on the Platform in the half-hour between my train's arrival and its subsequent departure :) The astonishing thing is, given that the bike was such a bargain - I did pay more than...

    Will a 36V Panasonic motor fit a Kalkhoff built to take the '24V' ones?

    Gosh, what a swift and courteous reply! Thank you. Much as I suspected though. I'll muse on :)

    Will a 36V Panasonic motor fit a Kalkhoff built to take the '24V' ones?

    Just musing at the moment, I don't have any plans to actually do this! I don't mean the Impulse motors, what I mean is on German e-bay there is, for example, this http://www.ebay.de/itm/Panasonic-Pedelec-E-Bike-Mittelmotor-Freilauf-350Watt-36V-NUA035HB-/321925212523 which I didn't even know...

    Sturmey Archer 5 speed hub - heavy duty

    It counts from the bottom. So gear (n+1) will have a ratio 1.25 times higher than gear (n), like the second example mike killay gives above. Therefore gear (n-1) will have a ratio of 1/1.25 = 0.8 that of gear (n). The direct drive gear on these, that is the wheel goes round at the same speed as...
