Just so that I can make informed decisions, how did the single bolt SP tests you've seen fail? My daughters Aventon hads a single bolt post (and, surprise, gives her trouble).

Thanks for all the great responses. To answer the question: I've left the shim in place, it has not loosened again in 250 miles, the rider is happy - so it will stay. Her seat is the factory seat, not "Loft". And her post is in the correct orientation (I tried it both ways - turning it...

no idea, but remove your battery and see if the battery lock is held in by two screws. If so, listen them (but don't remove) and see if the lock can be pushed in.

I'm not sure why you would ever need to do this, but just in case you do, here is a DIY on how to remove it. To understand removal, it helps to see what the battery tray looks like out of the bike: In the above photograph the battery tray has been disassembled fully, you likely won't need to...

Thanks @PHXRDR. Conclusion after a days work: removing the battery tray was ultimately not helpful - loosening the >motor< and letting it hang down by the rear bolt allowed the old cable housing to slide freely through the frame. I did need to disconnect the large plug from the motor to allow...

I've replaced the handlebar on my 2022 Ultimate T10 and now I must replace my shift cable for a longer one. This is my first real work on the bike (and first chance to buy tools). The current cable housing is too short, and is tight - like it's been zip tied somewhere inside the frame. If I...

Thank you everyone for all your comments, this has all been very helpful. I'll post a wrap-up when I get there.

The saddle and seat post are OEM, or at least they are what came from the LBS when she purchased it new. The seat has the Electra logo on it, the post is unbranded. She said the nose was uncomfortable. She's comfortable with it now, I'm just not liking the shim. If you have a recommendation...

She doesn't want 20 degrees downward, not sure how I implied that. Her complaint, all along, was the nose of her saddle was too high. Saddle height was ok, setback was ok, just the nose was too high. Lets re-frame the discussion: In the photo above, her saddle is nearly horizontal, and it...

I'm not sure this will clear anything up, and keep in mind I'm a rookie. Attached is a photo of her seat - it's currently adjusted to the "max nose down", yet as the first photo shows, her seat remains relatively near to horizontal. On two other bikes I've looked at, adjusting to "max nose...

I'm relatively new to the bike world and I'm surprised how much there is to learn about basic bike geometry. Today's challenge is my wife's seat post on her Electra ebike. Her combination of seat tube angle, seat post design, and desired saddle angle are the issue. Her saddle adjustment is of...

No shifting issues, no noise, I just wanted to do this for the first time so I know what to expect. The mess was a little larger than I thought :) For chain maintenance, I purchased a chain scrubber, I used purple degreaser (1:1 dilution) and a few brushes for the cassette and derailleur...

I've just reached 180 miles on my new ebike (Bosch mid-drive) and cleaned and lubed my chain and cassette for the first time. I've never done this before. I noticed the teeth on the sprockets showing wear, is this type and amount of wear to be expected after 180 miles?

I have the 2022 T10, taking @Roamers word on geometry, I'll add that a handlebar with more rise and (more importantly) sweep really made my 57 much more pleasant. I'm 5' 11" and 205 lbs (180 cm and 95 kg) and need a very upright riding position.

I'm wondering if a datasheet or other documentation is available for the controller in my 2022 Ultimate T10. I'm not trying to repair or modify anything, I'm just curious.

A touch of dielectric grease did the trick, no cutting required.

OK, chapter two... since I couldn't discern any movement from my front suspension using my body weight on the bars, I greased it with white lithium and set out to lower the preload. The adjustment is exactly as documented above: Don't miss the distinction between the five-sided and the hex...

I'm only 150 miles in, and a novice ebiker with no other bikes to compare it to, so my opinion may not count for much - but it seems well made, forgiving of my mistakes (well, all but one really dumb one), and highly adjustable. Unlike my wife's bike, I can draw the battery down to zero with no...
