Hi, those were really old posts...but, I am still having problems with my brakes and speed of the bike. I have also spent almost £200 trying to sort the problem out which includes a number of brake overhauls, fitting a new disc brake, having the bike serviced at a cost of £90 which has made little improvement to the problems I specified.
I have now removed my back brakes as they we causing so much trouble, the front brake disc brake also seems to be dragging the wheel, and the bike only seems to reach 13mph on throttle-hi speed and 11mph on pedelec and throttle-low speed, this is slower than my non electric mountain bike!
I am really not sure now what is causing the problems and have just spent £90 on a service which I hoped would resolve these issues. I had specified that I was concerned about the power output of the bike which was why I booked the service, however after I left my bike with the mechanic I was told that he could not in fact deal with any of the power issues, apart from checking the connections and putting Vaseline on them, which I paid almost £100 for!
He did fit circular lever things to the brakes and also replaced one of the brake cables, he also said the brakes were rubbing and had sorted this. Having now ridden the bike for a couple of weeks both brakes are once again rubbing but the levers are more effective.
I am now at my wits end with trying to sort this bike out and cant afford to throw any more money at it.
Any ideas/solutions folks???
