The Urtopia Carbon Atom combines a carbon fiber step-through frame, a 750W rated rear hub motor, and a removable 835Wh battery. This guide helps you decide if its power, range claim, weight, and riding position match your daily needs.

A quick buying answer
The Carbon Atom suits riders who want a nonfolding step-through bike for commuting, errands, and everyday paved or mixed-surface riding. Its torque sensor, rear hub motor, wide tires, front suspension fork, and suspension seatpost support a practical comfort-focused setup.
It may be less suitable if you need a folding bike, a very light bike for stairs, or a compact model for a small vehicle. The complete bike weight is 61.7 lb, before considering personal carrying needs and any extra equipment.
Price and available colors
The listed price is $2,499, subject to change. Tampa Bay eBikes lists the bike in Moonlight, Copper, and Olive. Confirm the selected color and configuration with the shop before placing an order.

Power from a rear hub motor
The Carbon Atom uses a 750W rated rear hub motor. Its stated peak output is 1,250W, with 90Nm of torque. A rear hub motor drives the rear wheel. It is different from a mid-drive motor, which transfers power through the bicycle crank and drivetrain.
A torque sensor measures rider effort and adjusts pedal assist to that effort. The bike has four assist levels. Throttle assistance reaches up to 20 mph, while pedal assist reaches up to 28 mph. These are stated capabilities, not permission to ride in every location. Check applicable local rules before riding.
Battery size and range expectations
The removable battery is an 835Wh LG unit rated at 48V and 17.4Ah. The manufacturer states up to 93 miles of pedal-assist range. That figure was tested with a 180 lb rider in ECO mode on flat roads, using pedal assist without throttle.
Real range can change with rider and cargo load, speed, assist level, weather, terrain, tire pressure, and riding style. Treat 93 miles as a qualified manufacturer estimate, not a promise for every ride. The supplied 48V 4.5A charger has a stated charge time of about four hours.

Comfort from the frame and suspension
The carbon fiber step-through frame makes mounting and dismounting easier than a high top-tube design. The bike has an 80mm front suspension fork and a 30mm suspension seatpost. This is not a full-suspension bike because the rear frame does not have a separate rear shock system.
The 26 x 2.4 Kenda tires add a wide contact patch for everyday pavement and suitable mixed surfaces. Comfort still depends on tire pressure, saddle position, rider fit, and road conditions.

Brakes, gears, and tires
TEKTRO hydraulic disc brakes provide the braking system. Shimano ACERA eight-speed gearing gives the rider gear choices for changing terrain and riding pace. The rear hub motor and the drivetrain serve different roles: the motor adds electric support, while the gears help manage pedaling effort.
Controls and visibility equipment
The 3.5-inch color LCD shows ride information. The bike also has USB charging, a front headlight, a rear brake light, and turn signals. These features can help the rider monitor the ride and communicate presence, but riders still need to use safe habits and follow local rules.

Complete-bike weight versus net weight
The complete bike weight is listed as 61.7 lb. The manufacturer also lists a net weight of 58 lb with the battery and 50 lb without the battery. The net figures exclude accessories such as the rack, kickstand, fenders, and pedals.
For daily planning, use 61.7 lb as the practical bike figure. Removing the battery may reduce the lifting weight, but the remaining bike is still not a lightweight folding model. Think about stairs, storage, vehicle loading, and how often the bike must be carried.
Fit for different riders
The manufacturer fit guide covers approximately 5 ft 3 in to 6 ft 3 in. This is a guide, not a guarantee of individual fit. Reach, leg length, riding posture, saddle height, and handlebar position can all affect comfort.
The adjustable stem gives the rider another setup option. Tampa Bay eBikes can help with a fit check and safety inspection. Call ahead to confirm the model and test-ride availability before visiting.

- Kickstand

Who the Carbon Atom may suit
This bike may suit riders seeking a step-through carbon frame, strong rear hub power, a removable high-capacity battery, and everyday equipment already fitted to the bike. It can be considered for commuting, errands, and recreational rides where a nonfolding format is acceptable.
The torque sensor may appeal to riders who want assistance that responds to their pedaling effort. The throttle can help with starts, but the stated throttle limit is 20 mph. The pedal-assist capability reaches up to 28 mph, subject to applicable rules and riding conditions.
When a folding or lighter bike may be better
A folding bike may be more practical for apartment storage, public transport, or a smaller vehicle. A lighter bike may be easier for riders who must carry it up stairs or load it often without help.
The Carbon Atom is nonfolding and weighs 61.7 lb as a complete bike. Its carbon fiber frame does not make the full setup a lightweight carry bike. Compare storage, lifting, transport, and charging needs before choosing.

Frequently asked questions
Is the Urtopia Carbon Atom a mid-drive bike?
No. It uses a 750W rated rear hub motor. The motor drives the rear wheel rather than transferring power through the crank as a mid-drive system does.
Is the 93-mile range guaranteed?
No. It is a manufacturer claim tested with a 180 lb rider in ECO mode on flat roads using pedal assist without throttle. Load, speed, assist mode, weather, terrain, and riding style can change actual range.
Does the Carbon Atom fold?
No. The Carbon Atom has a nonfolding carbon fiber step-through frame. Riders who need compact storage or easier vehicle loading may prefer a folding or lighter bike.
Does the Carbon Atom include GPS tracking?
Urtopia does not list GPS tracking or cellular connectivity for the Carbon Atom. Its app support is limited to over-the-air updates; choose it for its riding equipment rather than connected tracking features.
