4 Best Pedal Assist Bike 2025 in the United States

The Gotrax Dolphin 26" Electric Bike is a solid option for adults seeking a leisure or commuter e-bike. With its powerful 350W brushless motor, it can reach speeds up to 20 mph, making it suitable for city commuting. The removable 280.8Wh battery offers a range of up to 30 miles in pedal-assist mode, though it only covers about 15.5 miles in pure electric mode. Charging the battery takes around 5.5 hours, which is relatively fast.

The bike's aluminum frame ensures durability while keeping the weight manageable at around 28.58 kg. The 26" tires and front shock-absorbing fork contribute to a smoother ride on various terrains. The bike also features dual disc brakes for reliable stopping power and a Shimano 7-speed system for versatile riding options. Riders can choose between three modes: pure electric, pedal-assist with five levels, and manual pedaling.

The boost mode, which provides a 6 km/h (3.7 mph) push, is useful for reducing fatigue during longer rides. The height-adjustable seat and angle-adjustable handlebar enhance comfort for different rider sizes. Assembly is straightforward, and the bike comes with a 365-day warranty for added peace of mind. However, the range could be a limitation for longer commutes, and the bike's weight might be a bit heavy for some users when carrying it or handling off the bike. The Gotrax Dolphin is ideal for those looking for a reliable and flexible e-bike for daily use or leisurely rides across the city.

The Gotrax S3 16" Electric Bike is a solid option for those looking for a convenient and efficient way to commute or enjoy leisure rides. One of its key strengths is the powerful 500W motor that can peak at 750W, providing good speed (up to 20 mph) and power for various terrains.

The bike offers flexibility with three riding modes, including pure electric, pedal-assist, and normal cycling, which is a nice touch for diverse riding preferences. The 280.8Wh battery allows for a range of up to 25 miles in pedal-assist mode, though the pure electric mode reduces this to about 15.5 miles. This should be sufficient for daily commutes and short rides, but might require frequent charging for longer trips.

With a recharge time of approximately 5.5 hours, planning your rides around the battery life is essential. The foldable and adjustable design is another highlight, making it easy to store and transport, especially in tight spaces. Its high-strength steel frame provides durability, although it may add to the bike’s weight, making it less portable when folded.

The bike is equipped with 160MM mechanical disc brakes, which are reliable for stopping, and safety features like an automatic brake light, LED headlight, and rear reflector enhance night-time visibility. While the bike is relatively beginner-friendly, its single-speed setup might not appeal to those looking for more versatility in gearing. Also, the bike's weight of 24.4 kilograms could be a bit heavy for some users, especially when carrying it folded.

The included 365-day warranty provides peace of mind. It’s a good fit for adults and teens looking for a practical and eco-friendly commuting solution.

The HUDAMZKY KT D12 Bike Magnets Pedal Assist Sensor is designed for electric bicycles, offering an easy-to-install pedal assist sensor that enhances the riding experience by providing a smoother transition when pedaling. One of the standout features is the built-in dual Hall sensors, which ensure a more sensitive and stable signal reception, enhancing ride safety and efficiency. This is complemented by the intelligent recognition feature that differentiates between forward and backward pedaling.

The installation process is remarkably straightforward due to its split design, allowing riders to install it without removing the crank, using a simple steel ring to secure it. Additionally, it is equipped with a waterproof plug, making it durable in various weather conditions.

Its lightweight nature—only 0.08 kilograms—might be beneficial for those looking to maintain minimal additional weight on their bicycles. The pedal assist sensor is especially beneficial for those who prefer a DIY approach, as it offers easy installation and customization options. The sensor is suitable for all ages and fits a variety of electric bike models, making it versatile. The necessity to adjust display parameters like C1 to 7 on compatible KT displays may require some technical know-how that could be daunting for less experienced users.
