Couple of weeks running with this, has now made the cycle to work an absolute doddle.

Averaging about 18mph over a 13mile journey, which is absolutely fantastic as far as I'm concerned. In the car the journey took about 30mins door to door on a usual day; can do the journey in 40mins on the bike and not turn into a totally sweaty mess!

Probably was faster in a straight line on my old crappy road bike but the battery just helps to demolish the hills.

So far, very happy! tongue out

In the end, I went for a 350W rear hub motor.

Thats plenty good enough to acheive a solid 20mph on just about any incline, which to me (I'll probably get slated for this) but feels safer on the open road..

Photos dead, but from memory it was V-brakes front and rear.

This is what I'm using on mine, and tbh its no bad thing as it almost acts as a self deterent on the road not too go toooo silly.

A 250w motor with a 15ah battery would be fine, the 350w on mine is plently, plenty adequate for me I think

Bit of an update, coming upto 1600 miles ish trouble free...

Id been charging in the office as battery was obviously weaker for uphill return journey.

Annoyingly, my workplace pat tested all items and stupidly I volunteered the charger. It failed the PAT test, the earth was excessive but was still ok, and the guy passed it anyway but my work don't / can't let me use it as they know it's over the limit (failed)..

I've contacted yose power, who asked me to provide evidence that it failed, to which I replied prove to me it meets UK standards.

They have offered me a £25 refund, so I guess it doesn't comply.

Sooooo, I guess I need a new charger.

How on earth do I get one that's ensured to comply?
