Hi All, my Haibike EQ Trekking from 2013, the Sram Dual Drive 3 broke and I replaced the wheel so lost a lot of gearing so top speed is very slow as a result. Can anyone tell me what to replace to front chain ring to ? I don't know what the old chain ring was, maybe 36 t ? also the 9 speed...

The Conway looks great but it's higher maintenance, they should have used belts instead of chains for the reduction, they can stretch and it is a bit noisy. It's too expensive, it could do with being cheaper but all these bikes are over priced, most people just won't buy them. Do you still...

This leads me to believe the BH is putting out a lot more power than the Bosch, I have never experienced the Bosch lifting the front wheel no matter how steep, but knowing Bosch, they could have measures in place to stop this ? This can also happen if you carry a lot of weight on the rack...

You do have to be in the correct gear for the Bosch to be efficient and for it to pull hard on the steepest of stuff, it will mean peddling fast which may not actually suit the cadence for some people and perhaps this is the difference ? with my bad knees I find a faster cadence suits me best.

I looked up the neo xtrem, That is a pretty hefty motor similar to a Mac, how many watts being used ? you can be sure was more than the Bosch, and with a top speed of 20 mph. I can not believe this motor can climb 23% considering a magic pie motor @ 3kw was practically stalling at 3kw. That's...

14% isn't that steep a climb, I'm pretty sure most hubs 500 watts and over can do that for a while as long as the rpm's stay high enough. The Bosch can't do it on it's own simply because it's designed not to move unless there is pedal input. The Bosch is also designed to make you put in effort...

I would say the Bosch is a mountain goat, I wouldn't consider 20-23% grades small hills ! Granted, it required considerable pedalling to get up but it did it, you wouldn't do it without the motor at all. And it was hardly even warm to the touch, I'm sure the motor itself was warm but the casing...

I've seen d8veh give the Bosch good reviews before and on the sphere ! :) BTW the site has changes since I was here before , there used to be a section for Bosch drives, Panasonic etc, what happened ? I have not posted much since registering some time ago.

Sure in a 16-20 inch wheel a 10-12T mac for instance might climb just as well on 500 watts. I doubt in a 26 and not in a 28" like on the Haibike. A geared hub like the mac is fine for most people if you got moderate hills, it will do just fine, but if you got slow very steep hills or trails the...

I got this last Summer on E-bay, The build quality of the Haibike is fantastic. I've about 600 miles on it with no faults. It is rather heavy, the front shocks ,dynamo and Sram DD3 do add to the weight, and I'm not convinced the front shocks are actually effective. The Dual Drive 3 hub while...
