Hi, Jenny. I was directed to you in search of a battery for an Eshylala S9. This is a fat-tire folding bike with an in-frame battery. Would you have any leads on this? My thread is here: https://electricbikereview.com/forums/threads/eshylala-cliensy-s9-battery.47501/ Thank you.

A customer brought in an Eshylala S9 fat tire folding bike. I can't seem to find any info on this brand let alone parts. The customer needs a battery and replacement key, but I think he might be out of luck. Anyone here have any ideas or leads?

What I want to see with this test, is the BMS board actually defective, or is the pack out of balance and therefore won’t allow the bike to turn on. Both are good possibilities.

You can, though I’d advise only temporarily just to test the rest of the Bikes’s functions since the cells would be unprotected. One last thing. There should be a connector with ~11 wires at the BMS. Can you (very carefully) check the voltage between each adjacent pin? What I mean is pin 1 to...

What are the symptoms? Voltage at the battery terminals (both where the cells connect to the BMS and on the pack connector)? When re-building mine, the bike would turn on and run with just straight voltage (no BMS attached), but the charge gauge showed empty.

No. Alta ended up replacing the bike. We put an entirely new drive system on and the bike still wouldn’t run. I’m glad we only sold one of these bikes.

I think it has to do with Bosch using the small chainring. Gen 4 motors don’t seem to do this.

Gen 2 motor? I’ve noticed at certain cadences and effort levels that I’ll get vibration in the chain on just about every Gen 2 Cx or Speed motor I’ve ridden. It’s to the point where I consider it normal behavior.

@Haibike Rider, thanks for the info. That was my initial thought, as well. I'll try to put some more miles on their bike and see if it loosens up. @webcurl, not directly, but I have used a GoalZero Sherpa 100AC power bank with the Compact charger to make the last 15 miles of a 150 mile ride...

Anyone ever have a replacement motor come in with stiff pedaling? Sent the bike out with the customer thinking it would loosen up, but the bike came back. Not only is pedaling stiff (chain disconnected, the pedals stop almost immediately), but the bike is only getting about half the range...

The Purion mount should open. Take the screw all the way out, and you might still have to pry it open (sometimes the rubber gasket holds everything in place too well).

Having done some long haul rides, it would be great to have a "break" button that would allow the rider to rest their legs without having to stop (note "Break", not "Brake"). Perhaps the Walk mode button could be programmed so that if held down while above 5 MPH, the bike will maintain the...

I haven't seen anything that suggests a hardware difference between the Gen 2 Cx and Speed motors. I have two bikes, one Cx and one Speed, and both motors weigh the same, sound the same, and pedal the same. Only difference is at what speed they cut out. Gen 3 Active Line and Active Line Plus...

As for physical fit, any motor within the same generation will bolt on. You physically could mount the new Performance Line Sport motor in the place of an Active Line or Active Line Plus motor, just as Gen 2 Cx and Gen 2 Speed motors use the same housing and bolt pattern. Displays, batteries...

The app leaves a lot to be desired (though the totally offline navigation and re-route is a fantastic feature that is sorely missed on smartphones). I mainly use the app so that I can check the phone battery on the Kiox as my phone holder covers the top of my phone screen. It would be nice if...

That sounds like the exact problem I was having. Suntour sent a new pack under warranty, and that pack worked fine with everything. That bike has since been sold, and the customer hasn't reported any issues.

Got a new Simi in the shop, ran the battery flat on a test ride, but am unable to charge it. The battery has 3 lights with the 4th/top light flashing when I press the button on the pack. Plugging into the charger, I can hear a relay in the charger cycling about every second, but the light stays...

Sweet! And not a bad price, either.

We’ve now had almost 10 bikes come in with the same issue. take the sensor off, loosen the two bolts, snug them back up, reinstall. The one bike I torqued to spec came back, the rest I’ve done just by feel (basically a light turn until it stops) have all been good.

My Kiox is bolted on. No need to remove it for me, and also guarantees it won't fly off when hitting a drop in the pavement.
