What a damn shame. :confused: I asked about the 48v, because my Hydra's battery is a 48V.

Is it the same (no replacement) problem for a 48V battery too?

Cuz Vinny, why did you have to part out your Hydras?

I use Muc-off biodegradable bike cleaner. I spray it on and use soft bristle brushes to clean the bike.

My Kindernay will shift under load, but it doesn't like it. It was a bit of a learning curve, but I now pause my pedalling when I shift.

I suspect one of the main reasons Kindernay went out of business is they couldn't get their hubs to stop leaking. I'm on my second hub and so far it hasn't started to leak, although so far I've only put a couple of hundred miles on the new hub.

Did you have any problems lining up the front ring with the rear cog? I imagine if the 'chain line' isn't perfectly straight the belt will not stay centered.

32 pound battery. :eek:

Thanks for the link. 👍

The road and gravel versions look very similar to the new Cannondale Neo road and gravel bikes with the Bosch SX motor. I wonder if Cube and Cannondale are using the same frames.

Fully bled and the shifting is back to normal 🥳 TPEHAK, thanks for all your advice. It's much appreciated.

I've bled the system a couple of times and was able to get the upshifts (small lever) to go through the full 7 gear range, but now the downshift, which was shifting fine, only shifts 1 or 2 gears.:( I've downloaded the bleeding instructions from the Kindernay website and watched one of their...

I just hand cranked the shaft with pliers and it indented through all 7 gears, so it looks like (fingers crossed) that bleeding the line might solve the shifting problem.

When I had the wheel off I couldn't figure out how to shift the hub manually. The long lever, that shifts to an easier cog works fine, while the short lever, which shifts to a harder cog/gear, shifts normal in the easier gears, but as I shift upwards the throws become shorter and shorter, until...

I replaced the hub fluid and re-installed the back wheel. Unfortunately (but not a surprise) the hub will still not shift into 6th or 7th gear, so the next step is to bleed the upper gear line. The bleed nipple takes a 5mm wrench, which I don't have. I've ordered one from Amazon and it should...

Thanks TPEHAK....that's exactly what happened. It looks like there was enough fluid. I'll put in new fluid and see how it shifts. If I still have difficulty shifting into 6th and 7th gear I'll bleed the lines.

Last year I had a similar problem, with the hub not shifting into the highest gear. When I drained the hub I found that very little fluid came out. Once I refilled the hub the shifting returned to normal. Thinking that this may be the problem (again), I took the wheel/hub off and drained the...

Damn, I keep on waffling on purchasing this bike. Part of me wants to buy the bike right away, while another part of me want to wait a year to see if any problems come to the surface. It's not like I really need another bike. I already have 3 ebikes and two regular bikes, including a very...

Scrambler & TPEHAK, thanks for the responses. I'll try the manual rotation first to see if its the gearhub and then the bleed if needed.

I'm having a shifting problem with my Kindernay 7 speed hub. When I gear down to the easiest gear and then gear up I can only shift 5 times. The up shifter lever seems to have 'bottomed-out' and will not shift into the last two higher gears. I can't see any way to adjust the shifter and I'm...
