Re: Haibike EQ Trekking, Bosch drive.

@o00scorpion00o: Your bike has the inverted motor layout. Have you had a chance to test ride the newer Haibikes? If yes, any difference in handling, etc? No Didn't get a chance to test them out yet. They have an internal gearbox of some sort and I'm wondering if there is much resistance when peddli...

Re: I know why the Europeans are so slender.

Bosch get beyond the limit somehow as it's not 250 watts, it's 500 watts and 750 peak. I do believe higher quality bikes with hubs are also more than 250 watts. It pulls me up 20-25% a lot more than most if not all hubs can handle at the same power level and even bigger hubs would burn at the watts ...

Re: Bafang BBS02 vs hubmotor - Need to climb

I find the Bosch has enough power to get me up 16-25% but I would be peddling hard after 20% but I can do it where hubs would burn. The Bosch would be hardly warm after such a climb. The difference though is the Haibike has an S-ram Dual Drive III hub in the rear wheel so you got much greater gear r...

How about a chain drive kit, cell-man sells them now too, along with his frame mount batteries, the bafang 750 watt sounds to be powerful enough when you can use the bike gears.

Re: Bafang BBS02 vs hubmotor - Need to climb

I've no Idea if the Bafang 750 watt is as powerful as the Bosh but the Bosch will easily climb a 16% grade with only the 9 speed cassette on a Raleigh bike, at the expense of top speed of course, but I didn't find it bad at all on my 64 km trip in Germany last summer. I also don't know what tooth ch...

Re: New Bafang Crank-drives

Can anyone compare the bafang 750 watt to the bosch ?

The bosch is about 500 watts and 750 peak, but I find it very efficient, I've never felt it get warm or at least not the casing even after a 20-25% climb.

Does the bafang have a proper torque sensor yet ?

Re: Haibike EQ Trekking, Bosch drive.

I would be 95% certain it's the SRAM hub causing drag. The Raleigh bike I tested for over 60 Kms in Germany was a lot easier to pedal with no motor assistance. I am going to put a normal wheel on when the weather gets better to test and report back. Well make sure you think it through carefully. Th...

Re: Haibike EQ Trekking, Bosch drive.

I've put a lot of km on both the Sachs Orbit 2 speed and the later 3 speed/freewheel or cassette & derailleur set ups - both predecessors to the SRAM rear hub you have. You should experience no noticeable 'drag' from the hub, especially in the 2nd gear which I believe is direct drive. They are less...

Re: Shallow cycles V full cycles.

The leaf has about 20 kwh usable out of 24. Thing is though for the 100,000 miles if the LiMn204 has an 800 cycle life to what, 70% end of life, and charging to 70% and down to 40% increases those cycles to 2000 or even 3000 to end of life.

Shallow cycles V full cycles.

I am having a discussion with someone over charging the Nissan leaf to 80% when you don't need the full range, or even 70% and not below 30-40% if you don't need to. Steve Marsh from Seattle turned 100,000 miles on his Leaf a while back and has lost 20% capacity, so he would have to charge about 1,3...

Sounds like the Bosch drive is a ripper. would love to test one of these drives and compare it to the Bafang. Obviously with the 16.5mph max speed, the drive is designed for the EU market. I agree the 400Wh is heaps for this speed and power limit. 400Whr is all I would consider on the Bafang also. ...

Re: New Bafang Crank-drives

The big advantage for those in certain counties is that you can run a leagal 250 watt and still cope with 20% grade hills. In my experience 250 watt hubs struggle on steep hills. It's not just about the wattage, which isn't really limited to 250 watts any more, the Bosch is about 500 watts and abou...

For the type of bike the drive is fitted too, I think the economy was quite reasonable however under these conditions, it certainly isn't better than what you will see with a geared hub motor. Where this drive shines is firstly how the bike handles. Off road it just about feels like a normal mounta...
