Re: Q: How much resistance when motor is OFF

So have you tried riding at 15mph, whilst with assistance, and then turning it off and seeing how that feels? Try accelerating from 10-20mph with no assistance at all, then try it the same with motor (albeit it cutting out at 16mph). You'll think that you're pedalling through treacle when you push p...

Excellent, thanks for confirming that.
Why didn't I think of looking there first?
One less thing to worry about.

Re: Shimano STEPS battery, always shows 5 LEDs

These are smart batteries, the handlebar display only knows how many power-bars to show based on what the state-information is reported to it by the battery. Handlebar shows 2 bars, the battery should also display 2 LEDs - at least that's my assumption, that I'm seeking to have confirmed. Has anyone...

Shimano STEPS battery, always shows 5 LEDs

My STEPS battery always shows 5 LEDs - whether fully charged or pancake flat. The bar control/display shows the correct 1..5 blocks reflecting battery-charge state and remaining miles does reduce accordingly. So I know the system's working. I presume my battery should show fewer LEDs to reflect stat...

Re: Q: How much resistance when motor is OFF

I agree with the odd sensation when power tails-off/stops at the limit. On more than one occasion I've stopped to check that I don't have a puncture. When cycling on the Eco setting I am providing sufficient power (i.e. input power on the cranks) to ensure the motor is running at it's Eco-level-max ...

Re: Q: How much resistance when motor is OFF

The treacle feeling is just the extra weight of the hub and is centrifugal, if that extra mass was evenly distributed at the circumference of the wheel it wouldn't be so bad, but as the mass is central at the axle it is a heavier dead weight to move unpowered. Low gearing is needed until you are ro...

Re: Q: How much resistance when motor is OFF

Glad you're having such a positive experience with your Steps system,other than when switching off. The only thing I can think of is it still having to turn an idling geartrain within the Steps unit,though the ressistance would be minimal it's felt by the rider. How long have had the bike,what's th...

Re: Q: How much resistance when motor is OFF

Interesting comments, thank you. Today I rode with my Steps is OFF mode from the start. It just felt like a normal, if heavy, bike. However, switching off after having it on, still feels odd. So I conclude it's the lack of Steps power that makes it feel odd, not any friction/resistance in the motor....

Q: How much resistance when motor is OFF

Hello all, Just seeking observations from others here... I've a ShimanoSteps mid-drive system. When it's OFF there is some, a little but noticeable, resistance from the motor. It's barely noticeabl if I'm pedalling slowly, but start pedalling quicker/harder and it becomes significant - almost the fe...

Re: How tight to tension my Brooks swift leather saddle

Take it easy and tighten bit by bit. You don't want to overdo it. Take out all slack so that the leather is held stable, then add a little more tension and press down on the top with your hand. It should depress a little but not a lot. If it seems like it might be right, sit on it. Too saggy? Add a...

How tight to tension my Brooks swift leather saddle

Hello all, Summary: Brooks swift saddle. - Ridden for two years - Never tensioned - Rested for 2 years - Turned the tension bolt 180 degrees and it snapped. So, I've just replaced my tension bolt (after it snapped the first time I tired to tension it). Now the saddle has more a sag to it than I reme...

Re: Rohloff wheel build

Additionally you would need to have the pulling spokes correctly located on either inner/outer of the hub flange. Shimano specify which (inner/outer) they should be for their disc hub; I would assume Rohloff does the same.

Re: Bearing race wear or bent axle (in Dynamo hub)?

Hi Brucey, Thank you for your detailed reply. I hadn't thought of internal rust being an issue because the exterior looks in such good condition and there's no trace inside the races. Ball bearings are now removed from both sides, so I'll tackle the final disassembly soon. I have the correct socket ...

Bearing race wear or bent axle (in Dynamo hub)?

Hello all, Problem: when the axle is rotated there is obvious grating/grinding at the same position each revolution. The hub is a Shimano DH-s501 Alfine front dynamo and the grinding (above the normal dynamo notch-resitance) is once per revolution. This makes me think the bearing races (either the c...
