I bought my girlfriend a single speed Thin a year ago. When she powers it up, it always starts in the second level of assistance rather than "zero". This has caused several unfortunate situations as the crank tends to rotate when pushing the bike to park or remove from a bike rack and the sensor recognizes the rotation and wants to put it into motion. This happens even when you "downshift" back to zero before shutting off the main power; at re-start its back at 2.
My bike has an aftermarket controller and it will start at 0 when I power it back up. Is this an option using the stock controller components that came from Sondors on hers?

Hi I've just bought a pre owned fat bike, not sure of the exact model but it has the "Wendy" led controller.
I inverted the bike to swap brake pads (being careful not to damage the controller) but it began to rain very heavily so I left it in situ and when I came back to the bike after a day or so I couldn't start it, yes the battery was charged?
The screen was completely blank, no led's on the throttle.
then after 24hours the lcd screen showed the 'boxes' where the information should be but just the boxes no actual information, this screen is visible even with the battery removed, so I'm thinking rain penetrated the lcd controller whilst the bike was inverted.
Ive now opened the controller and left it indoors in the hope that it will dry, and will put it in a bag of rice to absorb any moisture from the circuit board, is there anything else I should try?

So I decided to go for a 52v upgrade on my Sondors Thin using the Luna Cycles 52V TRIANGLE PANASONIC GA 18650 14AH HIGH POWER AND LONG RANGE battery. I carefully measured and I thought I could just barely get it in to my Sondors Thin if I took out the bumpers for the stock battery and some of the cable guides. I got the battery and even after looking it I thought it would work (see attached photos). I used a Dremel to take out the bumpers that were in there and most of the cable guides in the top right. The battery looks like it was made for the box, dimensionally it fits like a glove, but (and I knew this was going to be the tough part) the hard box on the Thin just won't quite close even after my modes. I don't think I'm close enough to quite get it there either.
I really like the look of the hard box case on the Thin, so I'm trying to figure out it:
Is there some alternative idea to getting this thing to work in the stock box. I'd thought maybe there's some way to modify the hinges... or even cutting off the outer rubber on the battery might save a few mm. Any ideas folks? That's why I'm posting on the forum. Is there another form of hard box, maybe from the non-Thin Sondors, that might fit in it? Is there something dumb I'm just not thinking of here? I guess the final option is just remove the box and put in a soft triangle bag (such as the Luna Cycles one). Does anyone have any experience putts one of those on the Thin? And once I do that I might as well get an even bigger 52v battery, right? I've also got photos of it compared to the ElctroBikeWorld LT48.
Appreciate any input anyone has. Thanks!

After upgrading the front crankset, rear freewheel, (53/17 final gear ratio), chain, LT48 battery, 20-amp controller and display the bike was a beast. Easily commuting to work at 26-27mph and hitting 28-29+ with a bit more effort. The issue was at those speeds in LA traffic I needed the ability to stop fast too. And re-adjusting my brakes every ~2-3 weeks was also getting annoying. The solution was new tires, hydraulic brakes, and Rotors. Here's what I got:
Rotors: Shimano Deore RT66 180mm 6-Bolt Disc Rotor
Brakes: PASION E BIKE MTB Hydraulic Disc Cut Off Power Brake E-Bike (This is basically just a Shimano Hydraulic brake set that's been modified to have the motor cut-off. Make sure to select the right option, in my case it was the second one from the left as my controller has the 2-pin (red) motor cut-off).
Rotor Spacer: Shimano F180P/P2 Disc brake adapter
Hose Wire Clip Clamps: Jiyaru Bicycle Cable Guide Brake Line Holder Hose Wire Clips Clamps (To route the hydraulic hose by attaching these to the existing closed cable lines).
Tires: Schwalbe Marathon Plus HS 348 Road Bike Tire
This thing stops like a beast now and with the extra traction from these tires this is a nice safety upgrade. Should reduce the changes of flats too as these tires have built-in tire-liners essentially. So far really happy with the upgrade. :)
I hope this helps somebody out!

I just assembled a new single speed "Thin" with the LCD control. It seems like its geared really low, especially when you have the option of the electric motor assist. When I'm going full bore, I'm pedaling like a mad man. What are the consequences of swapping the front sprocket for a larger one? I notice that Sondors' front sprocket has a kind of integral chain guard on either side of the chain wheel too. If I were to swap out the front sprocket and extend the chain, is there a supplier that makes a similar but larger diameter sprocket with the chain guard?
Thanks for any suggestions!
