hmm, that 1KW 48v DC motor sounds interesting! 40mph and hill climbing to 21 degrees :D

I bought my Arc about 18 months ago and used it every day last winter. I stopped using it in March this year and stored it in the shed with a full charge. When I started using the light again last month it lasted just as long as a normal charge so it has appeared it lost practically no charge in...

My previous electric bike was purchased from ec-bikes (website no longer working) Unfortunately it doesn't look like they are trading anymore so anyone out there with one of these bikes may find it quite difficult to get spares now. I've tried contacting the seller but they haven't replied to...

Excellent summary there Flecc, sounds like Giant were perhaps a little ahead of their time with the Lafree Twist. Sounds familiar..anyone remember Tivo!

Hi Jed, I have also got an Arc Li-Ion and it is a very good light. Not quite as bright as the Lupine Edison but very close and in fact, I prefer the beam pattern of the Arc. As you say John they are hideously expensive for a light but I've found that car drivers do give you more respect out...

Hi Eyesteel, welcome to the forum! This may be an obvious question but have you checked the battery still has a charge ? Flecc, was this particular model sold outside the UK? I'm wondering if there any owner groups out there on the net somewhere. cheers Russ.

Flecc's excellent summary of battery choice has been made into an article for the main site. If you'd like to read it, click on the link below: http://www.pedelecs.co.uk/articles/40/1/Deciding-between-NiMh-and-Li-ion-batteries/Page1.html thanks Russ

I think the problem now is the 'system'. We have built up such a huge global industry and economic system where corporate interests take precedent that unravelling it now would be almost impossible....unless. My own view though is that we will have to change and it will be forced upon us by...

Slightly old news as this was announced at the Eurobike show earlier this Autumn, but it's fascinating nonetheless. There is a good animation on the site that explains the technology in more detail: Fallbrook Technologies

From the Zero site they say: "The performance of the shaft drive system ranges from 90 to 95 % efficiency. In comparison, the efficiency of a good clean chain may be up to 98.5% efficient. Due to exposure to dirt and the elements however, the efficiency of a chain drive will reduce more...

Following your link, it appears the UK distributor is: zero cycles

Sorry Quicken, who did you contact ?

Hi Quicken, it has already been incorporated into an electric bike : Schwinn Bikes - Bike Detail The UK distributor Moore Large can order one in for you.

Hi Jonathan, those tyres are the same as I had on a previous electric bike. I was unfortunate enough to get a puncture half-way to work on the second day after getting my bike. I didn't really enjoy the 5-mile walk home! There are a million opinions out there on which tyre to go for, but I've...

Something I would love to organise at some point in the future is a Group Test. A logistical nightmare, but getting a number of owners together with as many different bikes as possible which can then be put through a series of tests to establish real-life performance. A bit like a UK version of...

Hi Tim, i'll add a link to that on the main site as I'm keen to have external reviews on there as well. cheers Russ.

Hi Gaynor, i'm currently working on a Buyers Guide for the main site that will allow you to compare specs for various models available and across suppliers too. I probably won't be able to get it finished this side of xmas though as the guide will also be using a 'Pedelecs' method of measuring...

For those thinking about adding Schwalbe Marathon Plus tyres to their Torq's I've been experimenting with different tyre pressures. The Marathon Plus is rated to maximum 80 PSI which with the Torq's lack of suspension gives a rather bone-rattling ride! I've found a good balance between...

If anyone is interested, a rather good book is available called: Electric Bicycles A Guide to Design and Use by William C. Morchin / Henry Oman Publisher: Wiley ISBN: 0-471-67419-2 It's pretty heavy reading and goes into great detail on the following subjects: Estimating motor-performance...
