Design

The CT20S boasts a futuristic yet retro-inspired design. Its aluminum alloy frame features a long, thick top tube housing the battery, with a minimalistic silver finish and black accents for a sporty and classy look. This aesthetic has drawn comparisons to Super73 bikes and even NASA moon exploration vehicles. The strategic addition of a handle on the top tube’s end allows easier lifting of the bike’s rear.

Motor and Performance

The rear-wheel hub motor delivers 120 Nm of torque, providing powerful acceleration and a top speed of 45 mph (after unlocking). While limited to 15.5 mph (25 kph) to comply with European regulations, the speed limiter can be removed for more thrilling rides. This motor is powered by a massive 60V, 27.5Ah battery secured in the top tube with a locking mechanism.

Range and Charging

In Class-1 PAS mode, the CT20S can reach up to 100 miles (160 km) on a single charge. However, relying solely on the throttle reduces the range to approximately 55 miles (88.5 km). Real-world testing showed a reduced range of 31 miles (50 km) when riding aggressively. Charging the battery from 7% to 100% takes about 6.5 hours.

Suspension and Brakes

The bike features a dual suspension system with an 80mm travel front suspension and a 180mm travel rear shock. Hydraulic disc brakes with 180mm discs provide reliable stopping power, crucial for handling the bike’s high speeds.

Tires and Accessories

Arisun moped-style fat tires offer decent shock absorption and light off-road capabilities, though they are better suited for urban environments. The CT20S comes equipped with fenders, a kickstand, and bright LED lights, including turn signals. An optional rear cargo rack and even a sidecar are available, though some accessory fitment issues have been reported.

Electronics and Controls

The CT20S includes a small LCD display showing speed, distance, and pedal assist level. A light sensor and cruise control add convenience, though the latter has been noted to activate unexpectedly at times. The bike’s horn and front LED light provide additional safety features for urban riding.

Pros

• Incredible Speed: Capable of reaching 45 mph after limiter removal.
• Unique Design: Retro, sporty aesthetic that turns heads.
• Powerful Performance: High torque and robust battery for impressive acceleration and range.
• Solid Braking System: Hydraulic disc brakes provide reliable stopping power.
• Dual Suspension: Comfortable ride even on uneven surfaces.
• Customization Options: Turn signals, fenders, and optional accessories enhance usability.

Cons

• Weight: At nearly 100 lbs, it’s not easy to lift or carry.
• Top-Heavy: The high-positioned battery affects balance at higher speeds.
• Pedaling Issues: Uncomfortable geometry and lack of a torque sensor make pedaling impractical.
• Accessory Fitment Problems: Reported issues with the rear rack and other add-ons.
• Reliability Concerns: Reports of motor noise and initial controller failure.
• High Speed Risks: The bike can feel unstable at its maximum speed.

Real-World Testing

Real-world tests revealed a mix of thrills and challenges:

• Assembly: Users experienced an initial error (“Error Code 30”), requiring a replacement controller.
• Comfort: The seating position is low, and pedaling feels unnatural. Most riders rely on the throttle instead.
• Range: Real-world range drops significantly with aggressive riding.
• Maintenance: Issues like chain interference with lower gears and motor noise arose, though Coswheel provided responsive customer service.
• Accessories: Difficulty fitting the rear cargo rack and other accessories was noted.

Who Is It Good For?

The CT20S is best suited for:

• Urban Commuters: Its powerful motor, turn signals, and fenders make it a practical choice for city riding.
• Thrill Seekers: Riders looking for high speeds and sporty performance.
• Moped Enthusiasts: Those who prefer a throttle-dominated riding experience.

It is less ideal for riders who rely on pedaling or need a lightweight, highly maneuverable e-bike.

Should You Buy the Coswheel CT20S?

The Coswheel CT20S is a high-performance e-bike with a striking design and exhilarating speed. While it shines in power and aesthetics, its weight, top-heavy design, and pedaling challenges may deter some riders. Reliability issues have been reported, but Coswheel’s responsive customer service mitigates some concerns. At its discounted price of $2,399, the CT20S offers good value for those seeking a moped-like riding experience.

For those who prioritize cargo utility or prefer a more balanced, reliable e-bike, alternatives like the Mokwheel Scoria or Super73 ZX are worth exploring.
