I hope there will not be an issue Flecc, as I do fancy using the Alfine again, maybe even the 11 on this project. However I would not feel easy making and selling bikes without the benefit of a manufacturers guaranty. As soon as I have news I will post. All the best David

I have just finished speaking to Shimano in Holland, they are not certain of the situation regarding the use of Nexus or Alfine with crank drives but have promised to come back to me next week. I then spoke to support at Madison. The chap there said that typically Shimano were very fussy about...

Hi Flash, great song but did he do it?

Hi Tillson, apparently, according to the guys at NuVinci, there is an issue with putting the torque created by a crank driven bike coupled with the torque created by the rider through any of the Shimano hubs in terms of warranty. This only applies to crank driven bikes, hub driven bikes are...

Thanks Flecc, I was a little uneasy about belt drives and splitting the rear stays is an issue, the manufacturers blurb seemed quite convincing though. You obviously feel that a lot of the new tech developers seem to be making a lot of claims that cant be substantiated in the real world. It may...

Too many e's and a's for me to possibly get it right Bob even with spell check! Why derailleur (I think) anyway, why not derailer? There should probably be an accent above the e too!

Thanks Bob, this really is the beauty of this forum, everyone wants to help! We wanted to use a carbon belt drive which of course would negate the use of a cassette and derailiure. Does anyone have experience with them?

Thanks Flecc, we are still considering our options, I have only tried an 905Alpino set up with the older version NuVinci. As you know we decided to stick with Alfine8 which was superior in every way. My worry is the possibility of no warranty support from Shimano (sill no response to my...

Thanks, Indalo, however Flecc is certainly the master of diplomacy, judging him by his resonse! We have had great success with hub motors which have proved to be very reliable thus far, in fact I don't think we have had to replace any nylon gears apart from on the very early bikes. We will...

And of course they are more suitable for riders who prefer throttle only? I also believe they are easier to maintain? Being less expensive they allow manufacturers to spend more on the traditional bikey bits, or providing better service! :) All the best David

Hi Hech, here is the link; Endless-sphere.com • View topic - RMartin R10 running at 1800Watts through Nuvinci N360

I can echo that Tillson's remarks, we have sold 1000s of Alfine Hubs now without one single internal gear problem. I should also add that we have not had any issues with the frame due to the front motor pulling the bike along, in fact I think the drive being split between the rider power at the...

I agree Bob, I have just emailed them for clarification but they did seem professional and on the ball.

I was talking to the guys at NuVinci a couple of weeks ago, they told me that Shimano were not going to apply their warranty to hub gears when being used with the Bosch system and this may extend to all crank motors. This was due to hub gears collapsing due to the extra stresses caused by the...

One man's shelter is a following man's shelter, ad infinitum! :)

Very classy, as with their suppliers Bob! :)

Hi Killjoy, it depends on whether the motor is has hall effect or not and then if there is a speedo on the bike. I can only talk about Wisper bikes but depending on the model there can be 3, 4 or 8 wires. On 26" rear wheel drive bikes we use a hall effect motor that has eight wires...

Sorry Rog, wrong adjective, I should have said many, many, many years! :) All the best, David

I know Bob, of course I would never expect that level of classiness! ;) All the best, David

I too have pondered this, it is the same in Germany, the flatter the terrain the more electric bikes are sold. I think the reason is simply people who live in flatter areas are traditionally more likely to use a bike, hence there are more bike users in these locations. Therefore there are more...
