That would include:
- motor with reduction gear and freewheel;
- seat post with the controller inside;
- 20ah 30V 8S LiPo (only 10 cycles);
- battery bag
- large-screen CA;
- control "magic button"
- the sprocket that is mounted on the BB spindle. The Hollowtech BB you can order on any of the...
Do not forget the wind :)
if I go by the lake with very mild inclines - it takes me almost no efforts to keep 30km/h (my max gearing) even on my off-road tires...
By the way, I am prepared to sell the Gruber kit + battery in the bag separately!
Since my employer is relocating myself to Dubai (no biking there) - the subject bike is for sale!
Price: 3,000chf (50% of new price).
Condition: almost now, 5 cycles on the battery.
I will most likely sell it locally, but if anybody has seriously interest - may dissassemble and sell the Gruber...
Here are the stats:
1. 20km flat + 18km uphill
Average watts: 100-150W (150W at high cadence of 80 rpms).
Range: did over 70km (40km flat + 18 uphil + 18 downhill) on 10ah. So my range shall be around 150km, but need to train my butt first to achieve that :)
I do not need it...
Actually, I quite like the logic of Gruber controller - the lower the rpm, the lower is the amp limit. You only get 150W at max rpm... and if you select the wrong gear, the load is 100W or even down to 50W... If you externally prevent pedals from turning, it shuts off.
10W was at 80rpm on the crank and high gear on the deraileulers. Though, I have pretty good crank (Shimano XT Hollowtech) and rear hub (Mavic).
Will test the real-world figures under full load tomorrow.
Finally the (huge screen :lol: ) Cycle Analyst arrived... and perfectly setted on the bar.
I was right, this thing is very efficient - free spinning of the rear wheel in the air takes 10W :)
Haha... electrically adjusted seatpost with memory :))))))
On the Gruber... I will be moving to Dubai in 2012, so will be selling the Gruber bike at some point. The bike will come with 20ah battery, Topeak battery bag and large-screen Cycle Analyst.
I will be asking for 50% of the new price.
I concur, it is noisy. The latest (v3.15 from 2011) is promised to be half-noisy.
But the voice helps. And by the frequency you know whether you are in the optimal gear, or not.
Brief after testing in the real mountains: it is something. The steeper the uphill - more you feel the help. I could...
