I am getting 32-35 miles per charge on my Neo Carbon regardless of mode or hills. Is this considered good, bad, or spot on?

I understand. I am very happy with the range. I wanted a fail safe range where I could use the motor as I pleased and be assured that I would not run out of battery. That appears to be 30+ miles.

35 miles on a 12ah isn't too bad.
With all due respect, for your age, that's terrific.
Key points worth mentioning.

- Tyres pumped to optimal psi.
- Brake rotor is not rubbing against the caliper.
- Chain is well lubricated
- Starting the bike on a low gear and then changing to high gear to gain speed.
- Not running the battery until last bar.

What is wrong with running the battery to the last bar? In fact, on my tablet and phones there is a protection circuit that prevents the battery from dying altogether when the charge is low. Not sure if my bike battery has this feature. Education please!

Hi 86,
Here is a good discussion about it:

That is because, the discharge voltage drops to 34ish instead of the standard 36v.
Most ebikes operate this way unless a special BMS is designed to compensate this.

Thanks for sharing this, Ravi. This is good to know ...
Just want to reiterate Ravi's advice about not running the battery dead. Deep discharges will reduce battery life... This is a well known phenomenon documented by battery manufacturers. I also know this from personal experience, charging two batteries over 1000 times over the last 5 years.
Car manufacturers are painfully aware of the impact of fully charging and fully discharging have on battery pack longevity... Most of their smart chargers will not charge the batteries past 90% or below 20% state of charge.
Cellman DIY kits are the only supplier that I know of who provides selectable battery chargers.. You can charge the battery to 90% 95% or 100% state of charge.

I was getting a safe 50km (~30 miles) per charge out of my 36v 12ah until recently when the some of the cells screwed up. On that day I certainly earned a beer when I got home after having to ride the 17kg+ bike home without any assist for the last 5km or so... Good news is the Australian BH dealer / distributor replaced the entire battery without any fuss.

Glad to see the dealer stood behind the product. A significant factor for repeat purchase is based on quality of post sale support from the manufacturer and dealer.
I get 30 miles at a minimum so far under all conditions (never used the throttle though). I do notice that when I hit two bars the amount of assist drops. This is pretty normal though.

86, does your bike have a 9ah or 12 ah battery? What would you estimate your average cruising speed is?
I think 30 miles is pretty good range for any eBike.

12A battery and I average 18-20 mph

That sounds good. My son says that on eco mode 30 + seems reasonable. He has young legs too. I rode around with him yesterday, and he races about 25 mph the whole time.

Being a long time motorcyclist you get used to never testing mileage. You set a range that is a failsafe distance and then simply fill up or recharge. For my 12A Neo Carbon that is 30 miles. I may get more mileage but I do not want to run the risk of total battery drain. If you use for commuting, you get in the habit of pulling the battery and charging at work. A solid investment is another charger. Some rides keep one on the bike so if they get stuck they can find an electrical outlet and charge enough to get to their destination.

I totally agree. I have a spare charger at my school. Even though when I get there, I've usually used less than half my charge, I always charge it back up, and when I get back home I charge it again. I've read that shallow charges are better for your battery's life than a lot of deep charges.
I told my son last night that he's probably going to want to buy a 12ah battery like yours. I'm very impressed with the Carbon. I feel like it's a very well made bike, without any particular issues.

My Neo Carbon is for sale with some significant upgrades including shifters and tires. PM if interested.

Sorry 86, it a little too late now. He already bought one.

If we're talking about Lithium battery's there's nothing wrong with running your battery all the way down, but it does shorten it's life. There's what's called "depth of charge". The less the, depth of charge, the less it wears out the battery, so a lot of shallow charges is easier on the battery than deep charges.
I don't have enough experience yet to say how big a difference it makes though.
