Lezyne do some really nice ones that are like mini track pumps and have a pressure gauge. All machined alloy, it's like a piece of art.

20.38 in Sport tonight, with a range of six miles still remaining. Pouring with rain the whole time, so i couldn't face finishing it off. Also the battery wasnt quite full, perhaps 95% charged. Should be ok for 27-30 miles in Sport i think.

Well technically a brushless motor will do a certain number of revs per volt, so more volts=more revs. So if you want the same power from lower voltage, it can be done, if there's more amps available from the controller to bring the watts to the same level, together with the gearing. All that...

Not so much the weight or the cable, more the lack of a quick release on the axle.

The Yamaha version appears to be last years model, and is only 26v, so the Bosch bike is more powerful with 36v.

I managed to run the battery out tonight, in Turbo, 20 miles exactly, fairly hilly miles. I expect the estimate of 24 miles would be achievable on quite flat terrain. Next, to find out what it will do in the next mode down, Sport.

I notice the Koga has a 38t chainring, whereas my BS10, obviously geared for more speed has a 44t, Cassette range is probably similar, but the BS10 could do with lower gearing for hills much over 20% for any length of time. I can muscle up short 30% inclines, but for no more than a minute or so...

Hard to argue against hub drive for mainly flat use. Crank drive really comes into it's own on the very steep stuff, where it takes advantage of the gears, or where you want more of a normal bike feel to the ride (high end torque-sensored CD).

A couple of minor niggles on the BS10 to report, one of the two stem-steerer bolts was not tight, the handlebar was also in the stem a little loose and creaked. Also a bolt holding one side of the front mudguard came loose today. All nipped up tight, no big deal really.

Wont go up the Rake with that high gearing :p

Yes, it's a company setup by the estranged wife and son of Mr Hon of Dahon. Good bikes, i had one last year.

Whoever Brose are, it sounds like it's more their motor with a Continental badge stuck on it. I'm not sure a tyre manufacturer inspires any particular confidence in a crank drive system. However more competition is always good.

I have this one from the Edinburgh Bike Co-op and it's been great over the years, even holding the Wisper's very rear-heavy 26kgs without issue. Head rotates so it will hold anything and it all packs away quite small. Revolution Tune Up Workstand

If i could do it without stopping i'd be in contention i think! Seriously though, 2.23 without electric demands massive respect. I'd have timed it if it wasn't too wet to have my phone out. I suspect 3.30 or there abouts.

Taff may be right, however if Italy does build this, i will be going there to ride it!

Other impressions of the BS10: This thing is fast, obviously. 25-27mph cruising on the third (Sport) and fourth (Turbo) power settings. The top power setting isn't actually a lot more than the one below it. On the second power setting (Tour) i find myself cruising at 15-16mph, but i can spin...

I have also noticed the cassette is an 11-34, so an 11-36 would provide a little improvement, not much though.

It's an Endeavour BS10, and today i took it up the biggest local hill, Holcombe Hill, which is off-road, bad surface and 20% minimum and 30% in places. I got up, but i had to have a break 2/3rds of the way up. The bike is geared tall, in fact it only spins out at 31-32mph. Bottom gear does 9mph...

If anything, the Agattu climbs the very steep stuff a little better because it's considerably lower geared. However both climbed a short, steep (30% is I would guess) gravel Hill with no problem at all. Yes I was aware of the wheel size trick from your earlier PM, thanks Dave. My dad doesn't...
