    Are Kalkhoff sprockets and chain specialist parts?

    I've answered my own question - the front chain ring is bike specific. Service parts can be obtained from Bristol - https://www.reallyusefulbikes.co.uk/

    Are Kalkhoff sprockets and chain specialist parts?

    Hi, I have a 2012 Agattu C8 Impulse which needs new front/rear sprockets and chain. Are these specialist heavy duty parts or is there an after market option? There are a number of ebike shops around the West Midlands, has anyone got a recommendation re where to take it? Thanks. Gerry.

    Kalkhoff battery replacement - supplier details

    My 2012 Agattu powerpack was supposed to be good for 1000+ charges. In reality I charged the battery no more than twice a week over a 3 year period. 150 weeks x 2 charges = 300. I haven't even allowed for 6 weeks a year when the bike was little used or not used at all as I was on holiday. The...

    Kalkhoff battery lights - top and bottom

    Hi Reggie, I have a similar problem with my 2012 Agattu. In my case the battery is probably nearing the end of its useful life. I've just spoken to an electric bike shop in the Midlands to ask about a battery refurb and in the course of conversation discovered that there is something called a...

    Battery Refurb?

    Hi, has anyone committed to a refurb of their original battery? I think mine (Kalkhoff) is giving up after 4 years use and I see there are a couple of outfits advertising battery refurb on ebay. My initial reaction is to doubt the likelihood of success but there may be someone out there who can...

    Kalkhoff Agattu C8 HS - no power

    All was well until 2 days ago when I found that there is no power to the on/off/pedal assist indicator and of course no power to the bike itself. My bike is about 3 years old. The battery charges up and holds a charge100%. Has anyone else experienced a similar problem? Gerry

    Kalkhoff Agattu motor issue

    Thankyou all for your replies, it's great to be able to share knowledge and experiences. In my case I have the Impulse motor and I'm delighted to say that theproblem eminated from worn pedal bearings rather than anything more sinister. If you haven't done so, try buying a decent set of pedals!

    Kalkhoff Agattu Impulse i8HS Bottom Bracket

    Hi, thanks for your reply, the chain rests very close to the base of the battery however in use it tensions and that isn't causing the noise. i've removed the chainguard and the noise is still there unfortunately.

    Kalkhoff Agattu motor issue

    Hi, My Agattu is about 18 months old and covers about 40 miles a week so has done around 3,000 miles total. The bike has just developed a very annoying ticking/clicking noise from the front sprocket which is of course also the location of the motor. There is no play in the sprocket or pedals...

    Kalkhoff Agattu Impulse i8HS Bottom Bracket

    Hi, My Kalkhoff is about 30 months old and has covered approx. 2,000 miles. Recently I've experienced a very noisy bottom bracket. It's making a very annoying and loud 'ticking' and 'clicking' noise which from previous experience with a Wisper pedelec precedes the bracket bearings packing up...

    Kalkhoff aggatu c8 hs

    Hi, I've just bought the Aggatu to replace my Wisper 905se. I'm very happy with it - it's good to have some brakes that actually work! I do however have an issue with the front wheel/steering head and I wonder if this is peculiar to my bike or if anyone else has had it. Imagine cycling on a...
