Sexy prices as well.

i dont like the integrated batts as in the wrong place and make the bike look huge and must add even more waight to the bike as none say how heavy they are.

the fs carbon bike i like but not the 12k price tag! i mean for what nothing special about the frame to make it cost that much and at 19kg its only 1.5kg lighter than my bike.

i mean if you bust that frame out of warranty or had to sell one so second hand the price will be loony money.

I love the intergrated batt look of some of these bikes...yes im shallow.

i want a bike under 15kg that can go 50mph for 50miles but cant be done yet.

Fascinating collection! Does it need to be so big though? Still trying to get my head round the differences between Yamaha and Bosch drive systems. The former seems to use 32-44 double chain rings and the latter single 16 front rings and a top guide wheel. Does that mean the Bosch system puts less strain on the chain? Presumably the motors internal gearing must be quite different to come up with similar torque figures (for what they are worth!) Also some models state the bike weight, others not.

There's actually two different versions of the Yamaha motor in their range, not all of them are the range topping PW-X. The more basic motor drops off power at higher cadences.

The small Bosch chainring is there so the motor doesn't have to be geared down as much, remember electric motors do very high RPMs, so to get them to a useful 60-120 cadence you have to put a gearbox in your crank drive unit.

The Bosch chainring turns about 2.5x for each rotation of the pedals, meaning it needs less gear reduction. The advantage of that is increased efficiency, less complexity and lower weight.

The downside is you can't use multiple chainrings.

Like dual battery option on hardtails, power tube plus powerpack.
