March 1, 201016 yr On derailleurs it's very easy Andy, just divide the smallest sprocket into the largest sprocket of the cassette/freewheel and then multiply by 100. Example on a 14 to 34 tooth freewheel: 34/14 = 2.43 x 100 = 243% .

March 2, 201016 yr Hi Andrew Would a larger chain wheel do the trick? We use a 54 on the tourer, I am sure I could dig one out for you. All the best David Thanks but I deliberately put a smaller chainring on to make climbing hills easier, My bottom gear is now the same as when the bike was new but I haven't got the 10 tooth step between 1st and 2nd gear*. Having the right gears at higher speeds is less important for me than having the right gears for when I'm going slowly. * After swapping the 14-34 Megarange freewheel for an evenly spaced 14-28 freewheel.
March 2, 201016 yr Chain Drive Thanks Russ! Andrew, if you need a smaller chain drive I am sure we can find one for you. All the best David
March 2, 201016 yr This thread is a little fiesty I find the three hub gears on my EBrompton more than sufficient, but then I live and ride in Cambridge. Regards Jerry
November 10, 201015 yr I can just see it now cycling down the main street at a steady 10 mph attractive young woman walking down the pavement, gives you a wee smile and the bike takes off like a scoulded cat:D hahahaha

Regards Jerry I ran away, turned into a bit of a playground, People with commercial interests should be very careful about slagging each other off in public. Just my 2p. Lovely sunny day today
November 10, 201015 yr The trade-off is that starting an ascent from a standstill requires more human input and feels much less "natural" than a drive-through-gears motor (which, by the way, also contain an internal reduction gear mechanism). Cheers, Dan [ That´s exactly what happened to me when I test rode an Emotion Urban 700 which has that kind of system! Even on the flat, the starting was more difficult and irregular than the non hub Emotion.
November 10, 201015 yr Crytalyte 5304 with a Lyen Edition controller, 72v @ 65Amps and 20Ah of A123 will climb just about anything.
November 11, 201015 yr ...and be just about the heaviest and hardest thing to pedal when the battery runs out! .
