    Optibike 2009

    It seems to be an electric scooter rather than an electrically assisted bike - so potentially an interesting development but off topic for this forum!

    Member of Parliament goes to work on an electric bike

    By a lot. If you go to the Netherlands, as I did in May, you would not be surprised by that figure.

    Switzerland and Italy Motorhome Trip

    Nice pictures, Eddieo. We had a holiday in Switzerland a couple of years ago, in Interlaken and down by the lakes, so those shots are very familiar! I remember seeing a lot of Panasonic powered Flyers even back then. From my experience, Switzerland is second after the Netherlands in...

    E-bike as mobility aid - advice please

    I think it's a great idea! I've sent you a private message with some more thoughts.

    Older riders - hilly areas

    I think you could do worse than look at Powabykes. They are great climbers and would be within your budget - probably even with a spare battery for the new X Series. The other obvious choices for hills would be one of the Panasonic motor powered bikes, Cytronex or an Ezee - but all I think...

    Cytronex lacking "go"

    My figures above were from memory, so I charged the battery overnight to check. I was actually underestimating quite a bit. The freshly charged battery gives no load of 20.2mph; before recharging the same battery gave 17.2. I think the numbers I quoted before were actually what I got...

    Electric Bike Magazines?

    Sorry Danny - my mistake! I was getting mixed up with this one Cycle Commuter magazine

    Electric Bike Magazines?

    That's not a stand-alone commercial publication! It's produced by Cyclescheme, the people who operate cycles-for-work schemes on behalf of employers, so you could say it is a kind of marketing literature for them, rather than something which needs to make a profit from. I read recently that...

    Cytronex lacking "go"

    Sorry to hear it's not quite working properly, Hal. For comparison, my no-load speeds for my 175 Tongxin are 17.4 when fully charged and about 15.5 after a 20 mile ride. That's with a Ping LiFePO4. Hard to know what your problem is. - It could be wrongly labeled. If it is a 160 I would...

    Thumb throttles

    It is interesting; I came across that thread a little while back while I was researching alternatives. I'm clearly not the only one who finds the normally supplied throttles un-ergonomic. Given that throttles are not that complicated - as far as I can see it's just some kind of variable...

    Ping battery charging

    You should leave it connected for a while - up to an hour after it first appears to have finished. You'll find the charger switches itself on and off a few times as the cells re-balance.

    What gears do you actually use?

    Completely agree!

    What gears do you actually use?

    I agree, and hope someone decides to make some soon! NB if your chain is coming off when you shift to your top gear, it sounds like your chainline is wrong and you need a slightly longer bottom bracket (excuse me if you know all this and have tried it already or ruled out for other reasons). A...

    What gears do you actually use?

    Flecc's post explains why the solution (a cassette) isn't a solution; the other point is that the problem doesn't seem to be a problem! Freewheels are most likely to break when subject to greatest force and this would seem less likely to happen on an electric bike where there is a motor to...

    What gears do you actually use?

    That gives you something like a 24" gear - almost as low as mine! Just what you need for tackling hills without taxing your knees.

    E-Rockit

    Probably. But some controllers work differently and it could stop teh bike working altogether. You really need to talk to someone with the same type of bike, or experiment!

    What gears do you actually use?

    You just need a screw-on freewheel. Spa Cycles have a Shimano one for £20 here The Sun Race ones may show up cheaper elsewhere (eg eBay) NB I'm talking about 13-34s, the 11-34s don't seem to be available anywhere. Make sure you don't get a cassette - some of those you've seen may be.

    E-Rockit

    In fact one of the Ezee F-bikes was launched a couple of years ago with 8 different level settings for pedelec operation. I thought it sounded like a decent idea but some thought the knob they used to adjust it looked like the browning adjustment on a toaster (which it did!) and it seems to...

    What gears do you actually use?

    In fact, Steve, assuming you haven't changed the chainring on the Wisper, that 34T megarange gear on a the 52T chainring will give you exactly the same bottom gear as Mussels' modified set-up, which I believe is a 28 rear and 42 chainring - therefore you're not actually disagreeing at all...

    What gears do you actually use?

    It would give you one extra gear at the top end. If your current set-up is fine certainly not worth doing but if its slightly undergeared, then it might be just what you want. I'm actually looking out for a 13T to replace the 14 that is on my wife's bike!
