Just a quick update. Went out for a ride at the weekend and the freewheel began working again following some hard pedalling on a steep incline, then froze up again some time later following another incline ! Will try flecc's idea but looks like it's going back. Thanks again for the advice.

Ahh, now I understand. I looked to see if there was a problem with the freewheel on the back wheel but thanks for explaining this to me. It makes sense now. So you wouldn't suggest I try and unjam it ? Is it a pretty complicated job ?

Just to add previously I recall you could backpedal and the assistance would stop, now once the assistance has kicked in I can't back pedal as I meet resistance and it just keeps driving me forward for a time.

Hi Alex. Thanks for your reply. The bike is still under warranty. It recently had the rear sprocket replaced as the other one sheared off. Ran fine for a couple of days and then this. I'm not the most technically minded but I'm completely stumped !! It doesn't have a display.

Hi Guys, I have a Kalkhoff Agattu Impulse HS8. I love the bike but just developed a niggle and wondered if anyone had any ideas what might be going on - I'm hoping it's something simple ! Pedal assist is working fine until I ease off on the pedaling and I can feel it pushing my legs round and carrying on providing assistance ! It does this for about 10 seconds or so or until I apply the brakes. The effect is most pronounced when easing off from higher speeds ! I've had the rear wheel off and on again but that hasn't made any difference. If anybody has any ideas it would be a great help. Cheers, Steve.

Yes, so true David :-) The Wisper cut an impressive sight as it handled his over-generous proportions with ease ! Could have been smoking a pipe in his favourite armchair... He looked a satisfied customer as I pulled a wide one round him.

I'm exactly the same ! Always looking for a chunky hub, slab of lithium, feet freewheeling backwards uphill, or the reassuring flicker of a tell-tale LED ! The other day I saw a huge guy on a wisper smoking a fag and making a very lazy effort at pedalling. A poster boy for the 'Why Not Just Get A Moped' dimwits..though I suppose it's trickier to smoke through a helmet :-)

PM sent John.

If only Ezee did a 14 or 15ah LifePO4 battery I'd be slightly happier to part with 500 quid..

I don't know the size and weight of the batteries but I'm sure Dave at Kudos can give us that information. 2 10ah batts work out about the same price as Ping option but with greater flexibility. Dave also suggested I upload an image of a kudos battery so others can perhaps advise on the easiest way to connect it to an ezee bike ie. does the battery case need opening etc. China is a long way to exchange items but I've read people have had good experience doing this.

Very interesting info jhruk. Those Ping batteries sound great and that's brilliant after 20 months. Been talking to Dave at Kudos about wiring in a 10ah rack battery and keeping another as spare. Ping are sounding extremely impressive though and thanks Roger for explaining how to wire it. I think it's great that Li Ping offers such good after sales support. This is so important and alot of the others don't seem to get this, with grainy little images of wires and confusing instructions. It would only take 10 minutes with a good camera to make things clearer. Customer service swings it for me.

Hi Eddie. It's a fair point. I was getting around 40 miles out of my onbike 14ah lipo (which is nearly 2 years old now and still fairly good), so a ping 15ah is certainly tempting if it can perform to a similar level but over a longer period. I practically live on the bike though and it would be nice to have a battery that could maintain that 40 miles per charge or so for a good long period. Back in my youth, before a nasty bout of glandular fever led to M.E. which I've just about beaten (I thought my riding days were done, until I got the electric bike), I was riding in excess of 300 miles per week on the racer, so I'm a bit of a range monster, but I know there's a happy medium with regards to handling and a great clunking battery. Ps. having said all that, Roger (username Bode) has just kindly messaged me with some glowing feedback on the ping 20ah lifepo4. So there's lots of options which is great. Incidently his feedback on that battery is here... http://www.pedelecs.co.uk/forum/electric-bicycles/10046-new-ping-battery.html Decisions, decisions :-)

Thanks Jerry, I will do. I'll also message some of the buyers in his ebay feedback to see what their experience has been.

Incidently, I've received very prompt, friendly responses, with excellent english from the ebay seller I mentioned above. So I think I may take the plunge at that price..

The battery is a nice neat fit considering you've got 20ah there, and that range info is very encouraging. It becomes so economical with a decent enough range. Will keep you posted on how I get on with my replacement battery. Just in the process of getting rid of the car...which will make for an interesting winter ! E-biking is pretty amazing though and I'm kind of looking forward to giving myself no other option every day. Hopefully I'll still be saying that by january !
