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 NBPOWER E Bike PAS Pedal Assistant Sensor is designed to improve the pedal-assist feature of electric bikes by using a 12-magnet system. This system is quite beneficial as it provides a smoother and more responsive pedal-assist experience, which can be crucial for maintaining a steady riding pace and reducing the physical effort required when cycling. The sensor is built from aluminum and metal, ensuring durability and longevity, which is valuable for riders who frequently use their e-bikes or ride in various weather conditions.

One of the main strengths of this product is its lightweight design, weighing only 23 grams. This makes it a practical choice for those who are conscious about the weight of their bike and want to maintain a lightweight riding experience. Additionally, the installation process is simplified by its compatibility with the hall controller and its straightforward left-side installation.

There are certain limitations to consider. The product does not independently address key specifications like motor power, battery capacity, or range, as those depend on the electric bike it is paired with. Therefore, while it enhances the pedal-assist function, its benefits are best realized when combined with a compatible and efficient e-bike system. Moreover, it does not provide specific information about the levels of assist it supports, which might be essential for users who prefer customizable riding options.

This product would be most suitable for adult riders looking to upgrade or maintain their existing e-bike's pedal-assist system without adding significant weight. It appeals to those who prioritize a reliable and smooth riding experience, especially if their current setup already meets other critical specs like motor power and battery life.
