Put another way, any DC motor is also a dynamo - they are one and the same thing. So, when you apply a voltage to the motor a current flows through the stator windings creating a magnetic field which intereacts with the permanant magnets in the rotor - so causing the rotor to spin. As soon as...

It seems to me that these things are set up for that 'easy/lazy' cadence that you see on videos from Holland. To have the power reducing in the high 60's and have the bike dictate what my cadence should be would drive me nuts. I have contemplated a BB motor for a second bike but this (along...

Dunno, but 5500 miles on the single track lanes of West Wales (where even the flat bits are steep) seems OK.

Don't be mislead by the motor 'power' rating - it is meaningless. Almost any 250w geared hub will give enough assist to get up hills. That's what I've got and it's been hauling my 65 year old butt around West Wales for the last four years. Hub motors are nearly bullet proof, although you can...

Can't believe this hasn't sold yet. I have the same led unit, it also cracked has been repaired with self amalgamating tape and has gone 2 years no probs. A battery recell from Jimmy would be 2-300 pounds then you'd have a bike that could climb the steepest hill you want to throw it at. If I...

Think you're right to be cautious on e bay batteries. Some one with more knowledge will be along soon, in the mean time it will help if you say what the kit is. Have a look at the controller and give us the max. current rating. Also what type of riding are you hoping to do and how heavy are...

All you'll get from the bike shop is one of those useless little 'ting ting' bells. I got one of these, it's big, it's loud and alwaya raises a smile (could look out of place on an mtb I guess)...

It's worth paying more for a battery with known cells. Those cheap e bay batteries are likely to be generic cells and may even be ones that were rejected by manufacturers as not up to scratch. You could try BGA reworking. They can re-cell your existing battery with known quality cells, they...

Welcome to the world of the e bike grin:D There's plenty of beautiful Dorset countryside to enjoy. Just watch out for sudden bangs at the tank range - nearly fell off mine last year when they loosed one off just the other side of the hedge! For me, Dorset was relatively flat and the range I was...

Try starting with Hybrids (mountain bike/city bike cross) you can always add a stem extender to bring the bars higher, giving a more upright seating position. Try a Dutch style bike with swept back bars, very upright relaxed riding position, less reach to the bars. There's a company called 'On...

I also lost the walking bug when knees became untrustworthy. Converted my bike 4 years ago (leisure and utility) now done over 5000 miles and trips are getting longer. Take it steady and be kind to yourself, I think you'll come to enjoy it more than you know.

Lucky grandkids, such an introduction to the fun of cycling will stay with them all of their lives. Kids were designed to be in the great outdoors.

Not sure how it would work with cycle to work scheme, but a kit with a geared hub motor would be my suggestion. If you go for a 36v motor but overvolt it to 48v you get approx. 33% extra speed. So 19-22mph assist speeds possible. The winding speed of the motor is important and has to be...

Depends where you live. I've got 16 and use 'em all.

Lovely weather and got out for a circuit of the hills yesterday. 25miles and got home with 4/5 leds showing. There was no discernable sag on the steepest of climbs (there are a few), so carrying the extra weight seems well worth it. At this rate I can see the original Ezee battery going on...

So it seems that there is no current limit set as a default, not sure what that means. If the system runs well, and it does, with no current limit, why would the manufacturer put the option in? I'm struggling to understand this - just out of curiosity. So on a heavy climb, I assume that's when...

Didn't know it is Halfords either. However, just bought an Avid brake for the wife's bike, cheaper than anywhere else and post free - came in two days.

:D That's interesting to know. My kit, bought in 2014, is still battling on, though the battery suffers sag on the hills around here, I'm currently using it with a 2nd battery in my pannier. But when the time comes....... How do you change the voltage setting? Presumably this also alters the...

Use it - charge it. The more a battery is deep cycled the shorter it's life will be. Why go out with a partially charged battery and suffer range anxiety when you decide to go further than planned 'cos it's a nice day and the birds are singing?

Also what you learn along the way comes in handy should there be any problems later. If you've built bikes and/or you're handy with the spanners, you should have no problems. If you buy a complete kit it will be plug and play. If you buy components there can be connection issues but you'll...
