Way back when, I was learning mechanical drafting, we learned that direct (chain drive) was more efficient than shaft drive. The rational was that there was an unavoidable power loss every time you changed the direction of the delivery of power. The figure I recall was a 7% loss @ 90 degrees. I...

I use to use a Kodak digital camera that took four AA bateries. Even using the lithium diposibles, I only was able to take 20 high resoultion picture and two or three short movies before it died. Going to the recharagable Energizers was amazing. I could take over 60 high rez shots and more than...

Sounds like a decent deal to me for a like for like factory replacement.

I have never had the new Freego battery, with Samsung cells open. I have replaced switches and repaired wiring inside the old. I say this just to let you know of my experience with these batteries. The main dfference between the two batteries is the size of the new, better, smaller samsung...

If you have a magnetic disk that passes by the sensor, do this first. Check the gap between the magnetic disk and the pickup. It should be less than 5mm. Check to make sure the disk turns with the crank. Sometimes the little teeth that snug it to the crank axle break off. The only reason you...

I do not know the characteristics of the the o ring you seek, but you might find them at the plumbing section. Probably a lot cheaper too. As well, you could try your automotive jobber. They often have a display of bits and bobs, your o ring may be there.

Thanks for that I do agree with you on the warranty aspect. The maintence advantages only apply to those that are able. In a delivery persons world, you'd learn quickly but then down time, regardless, is money in that profession. The other thing is the genuine savings against your earnings with...

Firstly, I am probably going to get rocks and other missles hurled my way but here we go. I have always talked delivery riders out of an ebike. Why? - Because of the cost of purchase against wages earned. - The extra work required if the battery dies mid shift. - Cost of spare battery -...

Firstly, if your bike is under two years old, this should be a warranty repair. Secondly, you should have your battery voltage checked. A battery with damaged cells may show fully charged but not have enough power. In my experience with these bike what you describe could be the following and...

I am approaching 3,000 miles on my 2015 Haibike Trekking. It has the original 10 spd chain and gears. I am over 16 stone and use it in hilly country conditions. However, it has not seen any extreme mtb conditions. It sounds like the 5.0 model would have better suited your needs. In the big...

I think that we should just simply ignore this thread. As there has been no reply from the op, I believe this was a flame post. It was put here for no other reason but to stir a foul smelling pot.

Sorry in advance, I am not commenting on yourself singularly. There you have it in a nut shell - Didn't buy my bike (s) there but they helped anyway. Sorry to see them go out of business. Ebike shops make nothing fixing a bike under warranty that was not bought there. Even if they did make a...

No clip attached.

Actually achohol is not a particularly safe alternative either as it produces no visible flame when it burns.

Achohol!? Like street drinkers need another reason to steal your bike :D

It is amazing what a little fact based reading can do for yourself. I have, what is described to be had by many, "the Hindenburg impression" about hydrogen. You are correct about modern storage tanks being tough and that the gas is held in a much different way than steel pressurized containers...

Your comparison of petrol to hydrogen is correct. However, if you were still entangled in said bike when the hydrogen ignited, you probably be unhurt by the flames, right? It just doesn't look safe to me. Use of hydrogen as a common fuel source for cars and now, apparently bikes, is not common...

Careful what you wish for. Yes I ride an ebike on cycle paths but it is still restricted inspite of my ability to derestrict it. Nothing burns me anymore than idiots I see travelling at speeds 25mph or more. If we have have speed limits on shared paths they will be much lower than 15mph. You can...

Playing devil's advocate here: Hydrogen, as well as petrol, are both highly flammable. The automotive industry has gone through great lengths to protect fuel tanks against leakage and fire in case of collisions. Knowing personally how mangled a bicycle can get, when struck and run over by a car...

It was also interesting to watch Vettel apparently steer his car into Hamilton after he lost his wing. But I may be mistaken :rolleyes:
