The AIPAS C2 Xpress is built as a fast, efficient urban commuter: a high-step aluminum frame with 26″ x 2.0″ low-rolling-resistance CST tires, an 1100W rear hub motor, and a claimed 62-mile pedal-assist range. Think: skinny-tire speed and efficiency, not fat-tire SUV vibes.
With up to 90 Nm of torque, PAS speeds up to 28 mph, and a 400 lb payload rating, it’s aimed at riders who want a bike that feels quick and sporty on pavement but still has enough motor to flatten hills and carry real-world loads.
This review zooms in on what matters if you’re already close to buying: motor feel, range realities, comfort, fit, and whether the C2 Xpress matches your commute.

Motor, Speed & Power Delivery
The C2 Xpress is unapologetically motor-forward. It uses an 1100W external-rotor brushless DC rear hub motor, tuned through a 5-level PAS system and a sine-wave controller for smooth engagement.
Brand PAS data calls out:
- PAS 1: avg ~9.3 mph, up to ~62 miles
- PAS 3: avg ~17.3 mph, around ~45 miles
- PAS 5: avg ~28 mph, around ~25 miles
On the road, that translates into:
- Strong launches from stops, even with cargo or a heavier rider
- Confident hill climbing, with 90 Nm of torque and 26″ wheels helping maintain cadence on steeper grades
- Smooth power ramps with less surging than bargain controllers
With the system configured for higher output, the C2 can reach 28 mph without pedaling under test conditions. As always, you’ll want to set your speed and PAS limits to align with local e-bike rules.
Battery & Range: 48V 11Ah for Efficient Commuting
The C2 Xpress runs a 48V 11Ah battery (≈528 Wh by voltage x amp-hour), mounted in the main triangle for better balance.
Key battery specs:
- Capacity: 48V 11Ah
- Claimed PAS range: up to 62 miles
- Electric-only range: up to 36 miles
- Charging: 2A UL/FCC-certified charger, typically ~4–6 hours
AIPAS leans into safety:
- Certified to MSDS, UN38.3, UN3171, UN3480, UL2271
- IP65 waterproof battery rating
- Internal layout and thermal protection controller designed to cut power before overheating
Real-World Range Expectations
Using the brand PAS chart as a baseline:
- PAS 1 (~9 mph): up to ~62 miles
- PAS 3 (~17 mph): ~45 miles
- PAS 5 (~28 mph): ~25 miles
For real commuting:
- Expect roughly 25–40+ miles for most riders using PAS 2–4 on mixed terrain.
- Heavier riders running high PAS in hilly areas should plan around 20–30 miles on a charge.
For an efficient 26″ x 2.0″ commuter, that’s a very usable balance of range vs. weight.
Brakes, Safety & Electronics
Braking
The C2 uses front and rear mechanical disc brakes with 180 mm rotors and metal pads.
Brand testing claims the bike can stop from 28 mph in about 8.5 ft under their conditions, which is more about showing the system is spec’d intentionally for the bike’s speed and weight than a number you’ll try to replicate.
Mechanical discs don’t have the one-finger feel of hydraulics, but they’re:
- Easier for many owners to adjust at home
- More than capable for a 64 lb commuter with 400 lb payload when tuned correctly
Safety & Control
The rest of the control stack follows the same “commuter-first” logic:
- 48V LCD display with integrated USB charging
- Half-twist throttle (thumb throttle optional)
- Cruise control: reach your speed with the throttle, then hold the “–” button to lock it in until you tap the brakes
Combined with the UL2271 battery and published UL 2849 certification report, the safety story is a meaningful selling point if you’re storing the bike indoors or riding daily.
Ride Feel, Handling & Terrain
If you like a bike that feels quick, efficient, and precise on pavement, the C2’s setup is squarely in your wheelhouse.
- 26″ x 2.0″ CST tires roll noticeably faster than 3–4″ fat tires at the same power level.
- A 45″ wheelbase and relatively narrow tires give stable, predictable handling at commuter speeds.
- The front suspension fork (up to 70 mm travel per spec) smooths out rough patches, expansion joints, and light gravel without turning the ride into mush.
Where it shines:
- City streets and bike lanes
- Suburban neighborhoods
- Hard-packed paths, light gravel, and park trails
Where it’s less ideal:
- Deep sand or snow
- Technical, rocky singletrack
If you’re mostly on pavement and decent paths, the C2’s efficient tires and geometry are a real advantage over heavier, knobbier setups.
Comfort, Fit & Ergonomics
Despite being a high-step commuter, the C2 is designed for comfort across a wide height range.
Comfort features:
- Front suspension fork with ~70 mm travel and adjustable stiffness/lockout
- Ergonomic riser handlebar (~66 cm wide) for a slightly upright, relaxed posture
- Cushioned saddle and standard 170 mm crank arms
Fit window:
- Recommended rider height 5’2″ – 6’7″
- 32″ stand-over height favors average-to-taller riders or shorter riders who are comfortable with high-step frames
- Seat-to-floor range ~31–40″ gives enough adjustability for most riders in that band
If you’re under about 5’3″ and want both feet fully flat at stops, those stand-over and seat numbers are worth checking carefully.
Utility & Everyday Use
As a commuter platform, the C2 is set up to be “ready for work” rather than a bare frame that needs lots of add-ons.
Everyday utility highlights:
- Rear rack compatible (with rack and fenders offered in bundles) for panniers, baskets, or trunk bags
- Full fenders available to keep road grime off your clothes
- USB charging at the display so your phone or lights stay topped up
- Kickstand, lights, reflectors included in the core build
With a 400 lb payload rating and efficient road tires, it works well for:
- Daily work commutes
- Grocery runs and errands
- Campus or city transportation where a car is overkill
Pros & Cons
Pros
- 1100W rear hub motor with 90 Nm torque for strong acceleration and hill performance
- 48V 11Ah battery with robust safety credentials (UL2271 plus additional transport standards)
- Efficient 26″ x 2.0″ tires that roll fast and help extend range vs. 3–4″ fat tires
- Up to 62-mile PAS range under ideal conditions; realistic 25–40+ mile commuting range
- 400 lb payload rating, solid for a non-cargo commuter
- Mechanical disc brakes with 180 mm rotors tuned for 28 mph use
- Wide fit window (5’2″–6’7″), good for households where more than one person may ride
Cons
- High-step frame and 32″ stand-over can be intimidating for shorter or less flexible riders
- 2.0″ tires trade some cushion and traction compared with wider 2.6–4.0″ rubber on very rough surfaces
- Mechanical brakes need occasional cable and pad adjustments to stay feeling crisp
- At about 64 lb, it’s not the bike you want to carry up multiple flights of stairs every day
- Power and speed mean you’ll want to be mindful of local class/e-bike rule limits when using higher PAS levels
Who the AIPAS C2 Xpress Is Best For
The C2 Xpress is a strong match if:
- You’re a city or suburban commuter riding mostly on pavement or good-quality paths
- You want something clearly more powerful than a 500–750W commuter
- You prefer skinny, efficient tires over fat-tire “SUV” styling
- You’re within the 5’2″–6’7″ fit window and fine with a high-step frame
- You plan to use your bike for daily transportation, errands, and fitness rides, not just occasional recreation
Who Might Want a Different Bike
You might be happier with another model if:
- You strongly prefer a step-through frame for easier mounting and dismounting
- You ride frequently on rough trails, deep gravel, sand, or snow, where wider tires shine
- You want maximum plush comfort and don’t mind sacrificing some efficiency for 3–4″ tires
- You need something significantly lighter or foldable because you haul it up stairs or store it in very tight spaces
In those cases, one of AIPAS’s folding or off-road models (or a step-through commuter) will likely be a better fit.
Final Thoughts: Is the AIPAS C2 Xpress Worth It?
If your idea of a perfect ebike is a fast, efficient, high-step commuter that feels at home in city traffic and on bike paths, the AIPAS C2 Xpress belongs on your shortlist.
You’re getting:
- A serious 1100W motor with up to 90 Nm torque
- A 48V 11Ah battery with a credible safety story and realistic commuting range
- Skinny, efficient 26″ x 2.0″ tires that help you go farther on each charge
- A frame rated for 400 lb payload, with practical commuting hardware available in bundles
It’s not the right pick if you need a low-step frame or fat tires for loose terrain. But for riders who want an affordable, fast, and efficient urban ebike that feels more like an upgraded analog bike than a mini-moto, the C2 Xpress hits a very compelling balance.
