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 eliminates the front 2 chain rings which are more efficient, the DD 3 adds drag which is noticeable, however eco mode eliminates this but I rather pedal as much as possible and use the motor only when needed.
The performance of the motor is good, not nearly as good as some of the DIY hub motors I installed on my old bike but they were pulling 2-5kw from the battery ! but it was fun.
It does climb like a billy goat, I've taken it up 20-23% maybe more, granted at that grade of hill I need to pedal very hard but it means being able to do it compared to not, without the motor so the Bosch will get you up anything you're likely to climb.
Hub motors with their fixed gearing will not nearly be able to climb what the Bosch can simply because the Hub motor is a fixed singer speed, where the Bosch can use the bike gearing, greatly increasing the ability to climb. The hub motor will slow down and stall on steep enough climbs and all that power turn to heat. The Bosch will be far more efficient climbing because it's always spinning where it's most efficient. The Hub motor will climb the same 20-23% with much more power and may even burn by the time it gets to the top where the Bosch motor to feel was not warm at all at the top of that climb !
The Bosch which is actually a 500 watt -700 peak motor (not 250) gets around the ridiculous E.U 250 watt limit I bet by clever use of programming of the controller, the Bosch ramps up power slowly which might make the difference. It gradually reduces power after 15 mph to nothing after 17 mph, after that you're on your own.
I thought I would miss the throttle like on my old bike but When I tested the bike in Germany I was immediately impressed with the smoothness of power delivery and the matching of power to my cadence perfectly.
I also tested a Raleigh with Bosch motor in Germany over 40 miles and noticed it is more efficient to pedal without motor assistance because of the lack of Dual Drive III. Which proved to me without doubt that the DD III is not very pedal efficient. However the Haibike with DD III would be able to climb much steeper hills having the extra gearing compared to the Raleigh, but the Raleigh was able to climb pretty steep hills 16% with ease, but at the expense of reduced top speed, but I did find it nicer to pedal unassisted.
The DD III shifts brilliantly under full load but you need to back off the power a bit to change back down, I could see the attraction to the NuVinci automatic hub, but would bet it's even harder to pedal unassisted ?
I wish they had used 3 chain rings as normal.
I suppose Haibike never imagined someone peddling the bike without assistance and thought no one would notice it, but mostly I bet they themselves didn't notice it.
Haibike now have a road bike with carbon wheels weighing about 18.9 kg compared to 27 for my trekking bike ! I would hate to see the price.
Battery wise, well, I pedal as much as I can mostly, I do use the motor for hills, and so can get pretty good mileage from the battery, I estimate 70 odd miles give or take with good size hills and peddling on the level with no assistance,if using max power all the time maybe 20-30 miles with some hills.
I only ever charge to 80% and charge again when I get to 40%. this still gives me much more range than I would need in a day.
Only charge your battery to 80% if you don't need the full range, and do not store the battery at 100% ever as this is bad for lithium batteries, the ideal charge to store these batteries is 60%. Especially when the riding season is over.
When I come home and if the battery is below 60% I charge back to 60% and leave it there until just 2 hours before I go for a cycle, which I then charge to 80%.
Overall I am very happy with the Haibike, I do wish it was lighter and easier to pedal unassisted, but the smoothness of power and the ability to climb pretty much anything makes this really a wonderful bike.
