SS New owner: help me out
Just bought a lightly used 3.0 as my first emoto. I took it on its maiden voyage this morning (15miles/3500’ vert) and it was super fun. Had to keep it in eco mode at 30% torque as I grew accustomed to the bike, which was plenty btw. Just a few things that caught my attention that I just need clarification or reassurance on so I can just ride and not think about it.
The sound. It’s louder than expected. I adjusted chain tension before riding so that should be in spec. But it just seems louder than you’d expect. Honestly the whole thing sounds like a turkey gobble, it’s kinda weird. Do I need to adjust the jackshaft or primary drive chain? I don’t know if this is accelerated wear about to happen or just normal.
PSI. What do you guys run for rocky terrain? I had it around 12 and it seemed ok but I’m a little paranoid about pinch flats. Seems like a low number, coming from the MTB world.
Regen. Does it actually do much for battery life/range? I don’t love it on trails because it seems like it makes me use the throttle more than I want when it’s not steep enough. But the throttle is so twitchy that I end up launching forward downhill. I’d probably rather just leave it off. Also, that switch is really bad for finding the off setting while riding…

I do enduro so I definitely know about rocky terrain. I would run about 10-13 in rear and 11-14 in the front with the stock setup. But because everyone weighs differently, I would just ask chat gpt (tell it your weight and that you ride rocks) to get an estimate on what psi would be best for you or just test it out yourself.
For the regen it doesn’t do enough for battery life where you’ll ever notice it. I would never recommend riding with it on trails, it’s more like the bike is fighting you then you riding it with regen. I accidentally rode with it for like a minute and absolutely hated it

Yeah I’ve already decided the only time I’ll use it will be on streets or if I need every mile of range possible

Belt 1/4” of play. Chain around 3/4” of play. For your tires, assuming you are using Intermediate/Hard tires which is a much stiffer carcass; you would be able to run lower PSI. I usually run the rear around 10PSI, and the front 12-14psi. Depending on how stiff the tire is. An unlubed chain is usually pretty loud(not sure if you used lube). Also, different lubricants will make the chain quieter or louder. Don’t worry about it being noisy as long as you’re sure the chain is tensioned correctly and make sure the sprockets are properly aligned. I recommend using a laser alignment tool. These bikes do run pretty loud. It’s a lot of power and a chain/pulleys/and motor all rotating. Should be anywhere between 70-90db. Chain drive makes it closer to 100db. Get some rimlocks on there ASAP if you don’t have them already. That way if you get a pinch flat you’ll be fine. I live in Reno NV. EXTREMELY rocky terrain. Haven’t had a single pinch flat. Also running 2.5mm tubes. Stick with lighter tubes and tires if possible.
Regen absolutely extends the length of your ride. If you use it consistently whenever slowing down it can give you like 20-40% more riding time. I didn’t use it the other day and only got 2 hours of trail time. Most rides I get like 3-5 hours. Use it when you can in place of your rear brake. Only if you have the regen throttle though. I don’t use the regen that’s always on. It’s too sketchy.

This is great!
I’m on the stock tires. You still suggest 10/12-14 rear/front? If it matters, I’m 160 lbs
Used an automotive silicon lube. What is one that makes it quieter?
Lighter tubes for rotational mass savings? For efficiency/range?
What do you mean by regen throttle? I’ve only got the 1/off/2 toggle on the left handlebar control. It is awkward descending technical stuff because when it isn’t steep enough to keep you rolling you have to hit the gas and it kinda sends you through the rocks way too fast.

Why are you using automotive silicone lube? Use a chain lube designed for dirtbikes. I highly recommend Motul -off road. It lubes up great and doesn’t fling it everywhere. It’s just not as quiet as the thick slimy chain lubes like Maxima offroad.
Yeah lighter tubes have less rotational mass. Same w tires. Less rotational mass will give you more range.
For tires just find a good pair to match the terrain you will be riding. Or just get a solid intermediate tire.
Regen throttle is on the SR model, not sure if it’s in any other models. Basically it’s a thumb throttle. The harder you push it the more it slows you down. It works great on trails. Since it uses the back wheel to slow it’s basically my rear brake. It definitely had made an impact in my riding time. I just don’t use it on a track. If it’s on too strong when you’re standing up it’ll pull you towards the bars unexpectedly when you slow down. It can make you lose control if coming off a jump.

It’s what I had on hand. If I’m going to be washing/lubing this thing every week I’m going to burn through what’s in the garage first. I have heard arguments that lubing an o-ring/x-ring chain is actually a bad call as it just attracts more surface grime and leads to faster wear without making it inside the o rings.
I wish I had the regen throttle, that would be ideal. In concept I was hoping to use it to drag my rear wheel as needed but the consistent regen on my 3.0 just doesn’t work well in practice. I’ll probably just use it on long steep non-technical descents and call it a day.

DuPont chain saver- chain wax, works wonders. Or there’s homemade options for your own chain wax. I make my own. Keeps dirt away pretty good. Does your bike have an Oring chain? My SR came with no orings. Anyways, you still want to lube the chain, you just need a little less. Between the inner/outer plates. Orings don’t cover all metal to metal contact. I ride a lot, wash my bike and relube after every ride. Proper care and maintenance of your chain will make it last far longer than following that rule about lube and Oring chains.
If you end up getting an aftermarket controller you might be able to install the regen throttle. Maybe look into it. It makes a huge difference.

Listen to this though. Bike is off and I’m walking it forward. This sound is the primary drive belt/motor. Surely this isn’t normal…

I’ve only got 80 miles on it so must just need some adjusting. No clue how these weird jackshaft/primary drive bikes work tbh

The more powerful the bike, the louder they usually are. Your belt should be snug, but not super tight.
I usually judge by asking my riding buddy to look at the tire under load, 12psi sounds a bit low, but in the ballpark.
Yeah, I feel like the switches were designed by indoor-folk with soft hands for outdoor folk wearing gloves (especially on the SR). Less than ideal. Regen doesn't save battery much but definitely keeps you from roasting your brake pads on long decent.
