Why You’ll Love It

Trade short car trips for something more fun. CityRang 4.0 combines a big battery, punchy motor, and a practical step-thru design that’s easy to mount even with bags or a child seat. The fat-tire stance feels planted on rough pavement, gravel paths, and sandy shoulders, while the long-range battery keeps “range anxiety” off your mind all week.

Key Benefits

High-Performance Motor
The geared 750W hub (peaks to 1,500W) delivers quick acceleration for traffic merges and confident hill support. Pair it with the 7-speed drivetrain to keep a smooth cadence whether you’re loaded with groceries or cruising the boardwalk.

Long-Range Battery
A 48V 20Ah (≈960Wh) lithium pack unlocks up to 70+ miles of pedal-assist range or 30–40 miles on throttle-only riding. Charge on or off the bike—whichever is easier for your routine.

Fat-Tire Comfort & Control
20×4.0 in puncture-resistant tires and a front suspension fork flatten cracks, curbs, and cobblestones. Lower pressures add plush comfort; higher pressures sharpen handling and efficiency.

Cargo-Ready Utility
The step-thru frame and integrated rear rack make hauling simple. Strap on a basket, panniers, or a child/passenger kit (sold separately) and take up to 300 lb total payload with confidence.

Clear, Simple Controls
A bright 5.0″ color LCD shows speed, battery, PAS level, and trip data at a glance—day or night. Choose PAS 1–5, use throttle for effortless starts, set cruise for steady speeds, or tap walk mode to guide the bike up ramps.

Everyday Safety
Dual 180 mm mechanical disc brakes provide predictable stopping power. Built-in LED headlight and tail light improve visibility for early commutes and twilight errands.

Who It’s For

City commuters and campus riders who want long range, easy handling, and real cargo utility
Parents and errand-runners replacing short car trips with a stable, step-thru ebike
New riders who value upright comfort and a low standover, plus throttle confidence at stoplights

Use Cases

Daily Commute
Glide past traffic with PAS 2–3 for efficient 18–22 mph cruising; arrive sweat-free, lock up, and carry your bag on the rear rack.

Errands & Groceries
Load the rear basket or panniers with up to a week’s groceries. The fat-tire footprint keeps things steady at low speeds and over curb cuts.

Weekend Exploring
Hardpack trails, beach paths, and park loops are CityRang territory. Lower tire pressure slightly for more grip and cushion.

Safety & Care

Check tire pressure weekly for best range and ride feel.
Bed in your brakes during the first few rides; re-adjust cables after the initial stretch-in.
Avoid submersion and store the battery indoors when not in use; wipe down contacts after wet rides.
Follow local speed/class rules; unlock higher speeds only where legal and safe.

Frequently Asked Questions

Is assembly difficult?
The bike arrives 85–90% pre-assembled with a video guide. Plan about an hour to mount the front wheel/handlebar/pedals and to fine-tune brakes and shifting.

Can I remove the battery to charge?
Yes. Charge on or off the bike. The battery locks to the frame to help prevent theft; the key is for removal only (it doesn’t turn power on/off).

Can it carry passengers?
Yes, within the 300 lb total payload. Add a passenger pad and footpegs (sold separately) and follow local regulations.

Do I need to sign for delivery?
E-bike packages are oversized and often require a signature. If you miss delivery, contact the carrier to reschedule.

What’s the warranty?
EUY provides 12-month coverage on the motor, battery, controller, and charger. Keep original packaging in case a return or service is needed.
