I purchased an as new Jetstream from ebay a while back. Whilst its a nice looking bike and I am sure the suspension makes for a nice smooth ride I sent it back. My main reason was that I wanted to fit a front motor and the fork spacing/profile was wrong. As you say its quite large for a...

Lazy folk! Many people use e-assist bikes when the alternative given their physical condition, means that they would never even consider using a bicycle. I myself am an insulin dependant diabetic and without e-assist, there is no way I would have ever considered commuting daily the 10 mile...

That is an admirable aim and desire to help the industry. My initial post was of course mostly in jest. Whilst valid questions from someone starting out, the quality and depth of the questions did make me wonder whether the company had a deep enough understanding and experience to have any long...

That's a long story, that is probably best not discussed here :p Jerry

Sorry not recruiting but losing staff :( Jerry

No I am an ICT manager and work in the public sector, so these charges would help greatly to boost my apparent excessive salary and over inflated Government pension as reported by the national press ;) I should add a "smart" supplier would read back through all my conversion threads (and the...

I recently received yet another request from a supplier who wanted my advice on converting Bromptons to electric power. "Hi, just wondered if you would be willing to help us with some feedback? We are working on a conversion kit for Brompton bikes. Our main problem is the battery pack. What...

So what did you think of my home made battery Regards Jerry

Yes Eddie I think the poor English often gives that impression on first reading. However they have over 1000 sales and 99% positive feed back. I remain optimistic :) Regards Jerry

Once you get over the pigeon English, I actually found the post a good read and quite informative. Though it blows away my preference for small 36v 2.3Ah 2* (6s1p) A123 batteries lol Three years, 4000 miles and over 800 charge cycles and counting :) Regards Jerry

I had another email today for something that I purchased that was not ebike or battery related. --------------- Dear Jerry, Kindly inform you that your two packages were sent out on 18th Oct. 2012 and the tracking number are *** and *** by China Post. But I should let you know the condition...

I have found myself on the endless-spere forum quite a bit more recently. I think perhaps both have something to offer, though this one is often more fun to read :rolleyes: Regards Jerry

Re suspension I was muddled up with this and the Birdy which is fully suspended bother ends :o Regards Jerry

Yep as I said these are 349mm rims. E conversions always get complicated with small wheeled "compact" folding bikes. I have just checked again and it looks like it does not have suspension front or rear. Regards Jerry

It will be written on the side of the tire. I would say its almost DEFINATLEY 349mm. Best puncture proof tires in that size are Marathon Plus but be aware that they are weighty and will add another 0.5-0.7kg to the carry weight. Building a wheel is not a problem several people on here will...

Seems the problem of recent battery shipping restrictions out of China has been raised already. Endless-sphere.com • View topic - Ping Battery horrible shipping delays. Regards Jerry

As most of the manufacture is done in China as I have heard they will be taking it over. Regards Jerry

Yep the Tongxin Nanos are pretty much silent and are reported to run better in freewheel mode. The Tongxin Goldants are a little noisier but not much. These motors use flat steel rollers gears rather than the nylon cog/gears. Earlier versions of the Nanos did prove less reliable in larger...

The Tongxin Nano rear motors are on this page Jerry

You can still get the Tongxin Nano slightly heavier rear motors I think. You would have to email Diana Lin. The Goldant motors even though speced at 260RPM run a 16" wheel at 16.5mph with their pedelec only controller. I have one on my Brompton Ti and it is way quicker than my Tongxin Nano...
