Many thanks to all for your constructive answers new chain and cassette on order

Can you please help my Haibike Trekking 4 has now covered 1800 miles I am now having some problems gear changing and also chain jumping when using the 2 smallest cogs on the cassette . I suspect a new chain and cassette are needed my problem is do I change them on a like for like basis or change manufacturer and is it possible to change ratios I never use the largest gear on the cassette. Currently fitted is a Shimano hg500 11-42 teeth 10 speed cassette.

At last I can report some good news I have managed to locate a company that can repair or offer a replacement chargers for the s duro and I would expect others if you are having problems . I took my battery with a broken charging socket and charger no output they repaired the charger and fitted new plug to the battery and charger(the new plug and socket are 4 pin but slightly different to the original) they also said in the event of not being able to repair my charger they could offer me a replacement at a very good price .The company is called POWATECHNIC 01142438100 web site powatechnic.com. I found them very helpful and pleasant to deal with and reasonable prices I do hope this helps others that are struggling with e/bike charging problems

fuse in the plug is ok so power into the charger is good but no output just wondered if any one had had one of these chargers apart before I delve in

more help required, I have now checked the charger with a multimeter and can confirm there is no output from the charger the mains input is good can anyone confirm that there is and internal fuse in the (yamaha) charger before I take it apart or is the charger not repairable . mant thanks

thanks for your replies yes I do have a damaged connector on the battery probably this caused the short circuit if its a blown fuse then I will change it first all good advice a big thanks to all

help required with charging issue, whilst recently attempting to connect my Haibike trekking 4 to the charger after a short ride I experienced a large flash as i tried to connect the charger. The battery seems to be ok and still powers the bike but the charger will not re charge the battery does the charger have an internal fuse or have I damaged and will need to replace the charger and or the battery

thanks to all I think the way forward is to try a different pad the bike has covered over 2000 miles and the existing pads are showing very little wear

Hello , A good friend of mine owns a TREK e/bike he puchsed it new 18 months ago and has from the begining complained about poor braking he has raised the question on several occasions with the supplying dealer. He would like to fit a 180mm front disc to try to improve braking but the bike is fitted with carbon fibre front forks the dealer has warned him that this could cause the forks to snap . I should state the current front disc is 160 mm diameter . Has anyone out there experienced any thing like this before?

A massive thanks to all at pedelecs and to all who responded to my problem broken seat. I contacted CAB and then contacted the dealer who then took the matter up with Haibike . Problem solved a replacement saddle arrived Wednesday!!!

thanks for your reply the cost of the screw would be only a few pence but it has snapped off in a plastic housing impossible to remove without butchering the saddle. I don't think the dealer would be happy with that do you??

just a quick update:-contacted CAB and spoke again to dealer submitted photo's of broken saddle they have now lodged a complaint with Haibike awaiting a response will keep you posted and once again a big thanks to all who responded!!!! 11

thanks to all for your support and helpful comments and advice. I have reported the matter to Haibike and am awaiting a reply from them. I will post updates and hopefully a satisfactory solution and of course I will name and shame depending on the outcome it could also be praise for the dealer/Haibike many thanks

I purchased a new Haibike earlier this year have now completed around 650 miles without any problems then on return home from a short ride the other day noticed the saddle had come loose on inspection a screw has sheared also noticed stamped into the underside made in china. I then contacted the supplying dealer only to be told the saddle is not covered by the warranty has anybody had any experiences like this

HI , A friend has a jolt e/bike pedal assist only and would like to fit a throttle to help on starting from a stand still . These are available on the web is it possible to fit one of these without chopping or splicing any of the existing wiring or changing the speed controller. many thanks Niggle

Hi Adam have you managed to fix your powabyke yet? have been on vacation and not had time to fix mine yet chhers Nigel

Hi thanks for the reply have checked out the controller on e/bay its not the same as the one on my Powabyke Nigel

Thanks for the reply but I dont have the equipment or the electrical nouse to check this component,I am aware that buying a new printed cicuit board may not be the cheapest option but it should solve the problem as the mosfet is on this circuit board cheers Nigel
