Torque up 10 nm to 60 and not 70 odd as previously suggested. It looks good.

I'm really happy with my Bosch, I've about 150 miles on it in the last 2 weeks. !
 
I like it!!!
 
Looks good doesn't it ?

I don't get the small crank ? maybe internally geared, or maybe they use a rear hub like mine only more gears ?
 
what's it like to ride a "Hard Tail" electric?

I've only made a FS electric and at 80kph, I'm glad it has suspension. I use a smaller controller now and limit my speed to
53kph, but sill happy to have Full suspension.

You get used to it, a good saddle helps but I run high psi for maximum peddling efficiency which doesn't help. A full suspension bike would be a waste for someone who wants to pedal. You can lock it out but it's generally a waste.

My friend Pat has a full susp and on electric only it's the only way especially on bad roads.
 
look like a central heating pump

Hi o00scorpion00o

Mine did pedal badly when it was just a pedal bike, but now that I built it up as a ebike, pedaling with it is fantastic. None of the bounciness it had before. May be the added weight but I think something else may be at work here. I can easily spin with it well over 30 mph continuously and also over some significantly rough pavement without loosing any momentum as I would on a pedal only non suspension bike. Would not consider a hard tail now that I experienced this for anything above 100 -200 watts. For the extra ten or so pounds the suspension adds, it is well worth it IMO.
 
It's possible that the motor lifts up the suspension and keeps it stiff while you ride. I know my fork lifts up as soon as i hit the power. I'm not sure if that's the case with the rear suspension as well.

Yeah, hardtail ebikes are not fun over 20mph or so, 30mph is about where i will cry mercy, unless i've got a rear motorcycle tire like i did on my race bike..
 
That. Looks. Really. Nice. :mrgreen: :mrgreen: :mrgreen:

Now bring them to North America already. But at USA power levels @750watts! :lol:

I'd buy one in a heartbeat only because I'm just not that skilled at fabricating my own high performing e-MTB. :oops:

That is interesting, I never peddled Pat's bike, I wouldn't try not with a 10 kg ping attached.

I think some suspension bikes now, the very expensive ones have sensors that monitor the terrain and adjust the shocks and they also know if you are peddling.

Some of the full suspension bikes I saw in Germany were just amazingly light, but they cost 7,000 Euros ! :shock:

I'd love to see them bring out a 15 kg electric bike.

I heard they just can't keep up with demand, perhaps they are looking into building them over there ? Or maybe they figure they won't make money there as E-bikes are out selling cars here in Europe now. The E.U anyway. It's getting harder and harder to own a car here with the cost of motoring. So they make enough here.

I doubt the 750 watts is the reason they are not selling in America because most people not on ES would know the difference. I can assure you the Bosch is more than powerful enough, especially when it shuts off assistance at 17 mph. It will climb anything.

I can't see the 20 mph and throttle being allowed in the U.S if a lot of these bikes hit the streets, I just couldn't see 20 mph working in large populations. Just look at New York.
 
Yes But trek and Giant are big sellers here, that doesn't mean they will use the Bosch motor in North America ?
 
the usa market is huge why wouldn't they sell them here???
Trek are made in the USA!
also these are mountain bikes.. offroad use intended :wink:

Is the U.S market nearly as huge as here though ? considering the E.U population being much larger ?
 
maybe your right.. maybe bosch, yamaha, panasonic, etc don't want another 300million potential customers.. :roll:

HAHA 300 million is nothing! :p

I mean though seriously, if ebikes are out selling cars in the E.U that's a huge amount of sales, so I don't know what the market is like there, sure there are 300 million "potential" U.S buyers but there are 550 Million potential E.U buyers (750 million European). I can't imagine ebikes out selling cars in the U.S ?

I think it has very little to do with population and a lot to do with penetration percentage.

If Europe has a 10% population penetration rate (1 out of 10 will buy an ebike), then the USA rate is probably 0.1% (1 out of 1,000). In that sense, the US market is insignificant.

Anyway, it's a beautiful bike. I hope this Bosh design will become the standard or at least one of the standards. I too don't get the small crank.
 
Another factor in ebike success in the E.U could also be the tax, car owners are crucified here which simply wouldn't be tolerated in the U.S and rightly so.

It does make me laugh though when I read about people complaining about fuel prices in the U.S. Cars are certainly much cheaper.

Getting people out of their cars is no bad thing though and so much traffic on the roads when people could walk or cycle and make room for those that travel longer distances.
 
I think they are keeping the older generation motors for the trekking bikes and the likes of the raleigh bikes and the new motors for the so called performance bikes.
 
By "small crank" do you all mean the tiny "chainring" or sprocket attached to the crank? That thing is tiny? Does it spin faster than the crank? Maybe the internals increase the rotational speed of the crank to reduce torque all the way through to the "crank / chainring".

With all the real estate dedicated to that drive they should've put the transmission in there and thrown the rear derailleur in the trash where it belongs.
