Jasion RetroVolt Pro Electric Bike

The Wired Viper is an exceptionally high-performance 20x4 fat tire eBike that blurs the line between a traditional bicycle and an electric motorcycle. Featuring massive 72V 35Ah batteries and a dual-motor system capable of an 8,000W peak output, this "compact monster" can reach speeds of over 55 mph with acceleration so aggressive it can easily trigger wheelies. Despite its raw power, the bike offers a premium and stable ride thanks to high-end components like an Exsho Cowboy dual crown fork, 4-piston hydraulic brakes, and a highly customizable display that allows riders to tame the motor behavior. While it is likely too heavy and "unhinged" for beginners or casual commuters, the Viper stands out as a top-tier choice for adrenaline seekers who want maximum torque and long-range performance in a smaller, step-through frame.

The Velotric Tempo is one of the most unique lightweight city ebikes we’ve tested, combining an experience that feels natural with smart features such as Pulse Mode heart-rate training. In this review, we test the ride, tech, and real-world performance to see if this is the best lightweight commuter ebike you can buy right now.

The Heybike Mars 2.0 brings significant upgrades, transitioning to a class 3 e-bike with robust 20" x 4" fat tires, enhanced portability, a comfy suspension seatpost, and smart Bluetooth app connectivity. While it impresses in performance and style, minor drawbacks like basic components and limited app features prevent it from being flawless, but overall, it’s a compelling, innovative ride.

The KOTTO 750L e-bike boasts a sleek design, impressive battery life, and smooth suspension, making it a stylish choice with strong after-sales support. However, it disappoints with lackluster performance, speed limitations, and some cheap components. It’s best suited for riders who value looks, ride comfort, and safety over high speed or pedaling efficiency.

The RadPower RadRunner 3 Plus stands out with its bold design, powerful 750-watt motor, advanced suspension, and seamless accessory integration, making it an excellent utility e-bike for various needs. While it commands a higher price and has minor drawbacks like cable management and display readability, its quality and feature set justify the investment for urban riders.

The Volcon Brat stands out as an ebike with bold motorcycle aesthetics, robust features like 31 mph throttle speed, full suspension, and hydraulic disc brakes. While practical elements and durability impress, issues like ineffective fenders, non-integrated battery, and stiff suspension highlight areas for improvement. A top pick for motorcycle enthusiasts venturing into ebikes.

The Velotric GoMad is a short-tail cargo e-bike that bridges the gap between utility hauler and legitimate commuter, built around a 750W rear hub motor (1,300W peak) with 85Nm of torque, 20x4" Kenda fat tires, and a custom ride mode that unlocks throttle up to 20 mph and pedal assist up to 28 mph simultaneously, a combination that's rare in the cargo segment. The 802Wh battery, RST Guide hydraulic suspension fork with 100mm of travel, Tektro hydraulic brakes, TFT LCD display, and 500 lb payload capacity round out a spec sheet that punches well above what most compact cargo bikes offer, and Velotric backs it all with dual UL certifications, IPX6 water resistance (IPX7 battery), Apple Find My integration, and a 1,200+ dealer network for real-world service support makes the GoMad worth a long look.
