The worst thing for a biker on the latest and greatest racing bike, is to hear the dreaded sound of a mountainbike tire coming up from behind. It happens a lot where I bike, so the fat tires doesn't seem to slow them down all that much.

You are right and I stand corrected. I am from Denmark, so there is the cock-up :)

I may have the same problem, on my route I have 2 places were the climb is to steep for my bike. So I change to a low gear(45t x 19t) and push real hard at the start of the climb and that will get me over, but not without a drop in speed below 25 Km/h. The reason in my case is that the hub...

What bike did you try ? On pedelec 25 throttle only is for pushing the bike and cuts out at 5 km/h and on a pedelec 45 the cut is 20 km/h. What most dealers sell is Pedelec 25 and then throttle won't get you to 15 mph.

I once bought a specialized bike with a shimano WH-R550 wheel set, the bike felt heavy and sluggish. So I replaced them with Fulcrum racing 7 wheels and the bike was transformed into something nimble. So in my case I can feel the difference between two non assisted wheels. Now a ehub wheel does...

If you plan on spending most of you time unassisted and you should, then a hub motor is out of the question. The wheel set on a bike is very important and a hub motor compared to a normal wheel creates a lot of drag. I made the mistake of getting a bike with a hub motor and I have regretted it...

Me yes with the knowledge I have now. The only reason I bought a bike with a hub motor was because I didn't try one, but only looked at a pretty picture. If you mean eHomer, then he has a recumbent and I haven't seen one of those with a nose motor. If ever there was a bike that could use a...

Yes one can, but the price is too high in my opinion, if you plan on spending most of the time over 25 Km/h.

Yes If one is not used to riding a bike, then of cause you are going to be surprised when the motor cuts out. But if you know what you are doing, then there is no surprise. And I can clearly feel the difference between a hub motor and a £100 wheel set like for instance fulcrum racing 7. And...

Hub motors don't have a lot going for them in my opinion. They can't break or recuperate very well and without power they become a anchor around you neck. One of the most important parts of a bicycle is the wheel set, so if they are to survive as a product for people planing on traveling on the...

The drag that comes after the bike hits 25 Km/h

Wouldn't the solution for hub motors, be to program the controller with the profile for a normal wheel. I know that this feature would require extra power beyond the 25 Km/h, but all it does is to make the bike behave like a normal bike. So I don't see any harm in doing so.

To measure power on a bike you would need a power meter and most pro riders have one. They are very expensive, but very useful. As some of you know I have a rear wheel hub drive and if I had access to a power meter, I would have been able to tell the difference in Watt between going say 30 km/h...

First of all you have a newer version of the wheel, so bear that in mind. When in normal(+3) and going slightly down(Denmark pancake flat), I can hit 40+. So no problem. When in normal and on a flat stretch with no wind to speak off, I really have to hammer to get to 30+. For the same effort...

A 700c wheel moves at about 200 rpm at 25 Km/h. Since Bosch have disabled the cadence trick, couldn't you just splice a new cadence sensor into the existing grid, so that one would track the left and the other the right pedal arm ? A typical cyclist spins the pedal arms at sub 100 rpm, so if the...
