ChiBatterySystems Rebel Touring 72V 55Ah Battery on the Onyx RCR: Real-World Range and Ride Feel
April 19, 2022
If you ride an Onyx RCR with the stock 72V 23Ah pack, you already know the feeling: the bike is a blast, but range anxiety shows up fast once you start riding it the way it begs to be ridden.
I swapped in ChiBatterySystems’ 72V 55Ah Rebel Touring battery and put it through a real, cold-weather distance test. The goal wasn’t to baby it for maximum miles—it was to ride it like a normal person who uses Sport mode, enjoys some wide-open stretches, and doesn’t want their day cut short.
Why I Wanted the Rebel Touring
My stock battery worked, but 23Ah on a bike like the RCR always felt like the limiting factor. I wanted:
More usable distance without planning my whole route around charging
Less voltage sag when I’m rolling faster or giving it quick throttle bursts
A setup that still feels clean and OEM-like (no hacked-up cover situation)
The Rebel Touring is positioned as the “go farther” option. ChiBatterySystems rates it at 72V 55Ah (3960Wh), and they describe it as roughly 2.5x the range of the stock 23Ah pack depending on how you ride.
Unboxing and First Feel
The first thing I noticed: this pack feels substantial. It’s got a handle, it’s wrapped nicely, and it gives off that “serious upgrade” vibe the moment you pick it up.
ChiBatterySystems lists the weight at about 38 pounds, and yeah—this is not a dainty battery. It’s more like lifting a kettlebell than swapping a typical ebike pack.
Install: The Best Kind of Mod (Barely One)
Here’s the part most people care about: fitment.
I tested the battery in the stock tray first. It was close, but not quite clearing. The good news is you don’t have to cut the tray sides off.
What I did instead:
Pulled the stock battery and straps
Removed the rubber mat
Used a rubber mallet to gently open up the tray sides just a bit for clearance
After a few careful taps, the pack dropped in.
The biggest win: the stock battery cover still fit.
If you’ve been avoiding big-battery upgrades because you don’t want to permanently change the look of the bike, this is a major point in the Rebel Touring’s favor.
Charging Setup I Used
I paired it with ChiBatterySystems’ variable rapid charger for the Onyx RCR. What I like about this approach is having control over how hard I’m charging and how full I’m charging.
This charger offers:
2 / 4 / 6 / 8 / 10 amp modes
Charge targets at 80% / 90% / 100%
In daily life, that flexibility matters. Slower charging and not topping off to 100% every single time can help with long-term battery cycle life.
Rebel Touring vs Rebel Max (Which One Makes Sense?)
If you’re staying mostly stock controller and your main complaint is range, the Rebel Touring makes a ton of sense.
ChiBatterySystems frames it like this:
Rebel Touring: prioritize range, plus better-than-stock power feel
Rebel Max: prioritize power for people tuning the controller hard
For my use—mostly stock behavior with occasional aggressive riding—the Touring is the sweet spot.
The Distance Test: Cold Weather, Real Speeds
I did my range test in brutal cold—around 25°F. That’s important because cold weather can absolutely hurt performance and comfort.
During the ride I wasn’t crawling along at 20 mph trying to set a record. I had plenty of bursts, including higher-speed stretches when the road opened up.
When I finished:
Distance: about 35 miles
Average speed: about 27.6–28 mph
Elevation gain: about 1,142 feet
Moving time: about 1 hour 15 minutes
At the end of the ride, the battery was reading 71.6V. Using the rough rule of thumb that ~72V is around half, I was sitting at about 50% remaining.
Based on that ride pace—lots of real-world “I’m actually enjoying the RCR” throttle use—that points to a realistic total range in the neighborhood of about 65–70+ miles.
If you ride slower and smoother, you can expect more. If you ride harder, faster, with more hills, you’ll pull that down.
Ride Impressions: Smoother, More Consistent, Less Sag
Range is the headline, but the way the bike felt surprised me.
Compared to the stock battery, the Rebel Touring delivery felt:
Smoother through acceleration
More continuous under load
More consistent with very little sag
That “saggy” feeling you get when the pack is working hard just wasn’t as noticeable here. The bike felt more confident, especially during those quick bursts where you want the response right now.
What We Like
Huge real-world range potential for Onyx RCR riders who actually use the bike
Stock battery cover fit (no cover modification needed)
Minimal install modification (gentle tray bending instead of cutting)
Smoother, more consistent power delivery than the stock pack
Variable charger control (amps and 80/90/100% targets) is excellent for daily ownership
Things To Consider
It’s heavy (around 38 lbs), so removing/handling it isn’t effortless
You do need to slightly bend the stock tray for proper fitment
Your range will vary a lot with speed, temperature, terrain, and how often you rip Sport mode
If your main goal is maximum power for controller tuning, ChiBatterySystems’ Rebel Max may fit that mission better
Final Thoughts
The Rebel Touring battery upgrade changed how I think about using the Onyx RCR day to day. Instead of riding with a mental countdown timer, I can just ride—and that’s the whole point of owning a bike like this.
After 35 miles in freezing temps at a legit average speed, being at roughly half battery left is exactly the kind of result that makes the RCR feel less like a short-range toy and more like a real EV you can build plans around.
If you want maximum range with a clean install that keeps the stock look, the Rebel Touring is an easy recommendation.
