EU regs I’m told!

HELP can anyone tell me where I can buy a NEW battery for my Kalkhoff Impulse Ergo Harmony 2013. I need a 36v 17.5Ah 208Wh one (or near offer). Plenty in Holland etc but they can’t deliver to UK. HELP

Better. I use a Nuvinci, set to cadence, usually 74 (old timetrial habit) so there's no down to shift to. I notice this morning, after recharging and resetting the controller to 'factory default', that my usual 54 mile 'range' is today 34 miles! Also a recent battery check indicated a 20% drop in Ah from new spec. What I'm really asking is whether I can justify a new larger battery, or rather the outlay, and a Badassbikes delimiter?

Sorry, noncomprendo?

Thanks for that. The readings are - 41.4v fully charged; 33.1v discharged. Added to this the distance taken to discharge was 73 miles at Power setting (Kalkhoff Ergo) and the assistance pathetic, effectively the bike was using its lowest level instead of its highest - as displayed!

I have, of late, noticed a pronounced judder on start-off. It happens as I push the pedal down the first time to move off. The motor judders quite violently several times, sometimes shaking the whole bike, especially so if I maintain a light pressure on the pedal with the brake on, however the effect goes as soon as I am moving and doesn't reoccur if I slow down and then accelerate, only if I stop and start. On loose surfaces the judder causes the wheel to kick, fun on mud! In other circumstances I would say that the chain is jumping the rear sprocket (it's not!) as that's the feeling I get. Any ideas?

You're too kind! But seriously... .

My bikes battery is 7000 miles old and either it, or I, am getting weaker! Hills which I recorded as 10 mph plus are now 7 mph just! I've had my bike for 3 years todate and cannot believe that I've got so much out of condition in that time. So, is it the battery or me? (Be kind please!)
