    Sold to a fellow forum member in US :)

    Gruber Assist: 100W in the seat tube

    So anybody interested in the purchase? Since the Swiss franc is very strong now, I can make it $1,500. And the shipping cost will be reasonable.

    There is no Hungarian version of Gruber. Do you really think Hungarians can manufacture anything precise like Gruber? :)

    Gruber Assist: 100W in the seat tube

    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...

    Gruber Assist: 100W in the seat tube

    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!

    Gruber Assist: 100W in the seat tube

    1) I was pedalling lightly, delivering 50-75W. Gruber was adding 150W. 2) about 1000m+ elevation.

    Gruber Assist: 100W in the seat tube

    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...

    Gruber Assist: 100W in the seat tube

    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 :)

    Gruber Assist: 100W in the seat tube

    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.

    what's that?

    Finally... Topeak Mondopack with 8x4S Lipos, connecting wires and CA shunt inside. Weight is exactly 4 kilos.

    Gruber Assist: 100W in the seat tube

    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.

    Gruber Assist: 100W in the seat tube

    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 :)

    Gruber Assist: 100W in the seat tube

    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.

    Gruber Assist: 100W in the seat tube

    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...

    Gruber Assist: 100W in the seat tube

    There is no BIN pricing on the company's website because they do not sell directly, only through the network of dealers, who take care of the installation, maintenance (lubing the gears) and warranty. However, you can find the prices among the prospects (Download section). It is not marketed...

    Gruber Assist: 100W in the seat tube

    Ok, couple of things to clarify: - CA: I have ordered one with a large screen. I am not into races, thus I just need a tool. if you want to be stealth - order a Speedict box (it will send Current/Speed/Ah by bluetooth to your phone). My goal is to go with a steady pace into 10-15% uphill (which...

    Cyclone controller failure?

    Change the ORO handle for a simple 3 wire handle off Ebay. ORO is not reliable.

    Yup, I have ordered MondopackXL on Ebay from a UK supplier for $60 (with postage).

    Gruber Assist: 100W in the seat tube

    Thanks Adrian. I have ordered the Topeak MondoPack (http://www.topeak.com/products/Bags/mondopack) - it is larger so 8x4s should fit. Worse case I will fit 6x4S.

    Gruber Assist: 100W in the seat tube

    I do not have the CycleAnalyst (they delayed shipments) to measure how much current does it take. Gruber says 3-6 amps. It should give me 3-6 hours of constant 10-15% uphill at 10-15kmh. So best case - 90km uphill :shock: and at least the same downhill. This thing is very efficient - for...

    Gruber Assist: 100W in the seat tube

    Some pics as promised: The Bike on the evening after-work trip. Where is the motor? :) Waiting for a larger bag (4x4S fitted into the current bag - 10ah) "The Magic button" and my blackberry custom super-holder :)

    frame tube clamps for mounting motor?

    Gruber Assist: 100W in the seat tube

    Brief update: - got my HK order with 8 4S batteries. Shit, they are small and light! - put 4 into the saddle bag for 10ah, 30v. - did the usual evening route (about 10km long, 500m uphill) - very impressed: Gruber does not give you rest - you still need to pedal. But it helps you to keep a...
