Leoguar's Fastest Electric Bikes
Enjoy our fastest ebikes with a speed up to 28 mph: Trailblazer, Fastron SO and ST, and Zephyr SO and ST. Each bike ships set to 20 mph. A higher setting requires an authorized display change and may be used only where local rules permit.
What Makes a Fast Electric Bike Feel Controlled
Top speed says little about how a bike starts, climbs, turns, or stops. Motor placement and torque shape acceleration, while tire size, bike weight, brakes, surface, and rider input shape control. A faster setting also asks you to leave more braking room and make earlier decisions around traffic or changing ground.
Our all five models use hydraulic disc brakes, but their routes differ. Trailblazer pairs Shimano four-piston brakes with full suspension for trails. Fastron uses 26 x 4.0-inch tires and Tektro hydraulic brakes for pavement and firmer mixed surfaces, while Zephyr uses 26 x 2.35-inch tires and Tektro hydraulic brakes for city streets and firm coastal paths.
How to Choose Fastest Electric Bikes
Choose Trailblazer when climbing and trail control matter most. Its mid-drive motor is rated at 500W, reaches 750W peak output, and provides up to 100Nm of torque through a 10-speed drivetrain. The full suspension and 27.5 x 2.6-inch tires are built around trail use rather than relaxed cruising.
Choose Fastron SO or STÂ when you want a 750W rated rear hub motor, up to 1,000W peak output, 85Nm of torque, and 26 x 4.0-inch tires. SO uses a step-over frame; ST lowers the top tube. Both weigh 70 lb with the battery, so plan for storage and transport before buying.
Choose Zephyr SO or STÂ for a cruiser setup with a 500W rated rear hub motor, 750W peak output, 60Nm of torque, and 26 x 2.35-inch tires. The ST has the lower step-through frame; the SO keeps a traditional step-over shape.
Speed Changes Range and Access
The five bikes carry 720Wh batteries, but a battery size cannot promise the same distance on every route. Higher speed and assist, frequent starts, climbing, load, wind, temperature, tire pressure, and surface resistance can all shorten a ride. Use each product page's range information as a planning reference and keep reserve capacity for the return trip.
Rules for electric bikes differ by state and can change between streets, paths, and trails. Confirm current state and local requirements before changing a speed setting. If 20 mph meets your route and local rules, leaving the factory setting in place is the simplest choice.

Frequently Asked Questions
Trailblazer, Fastron SO, Fastron ST, Zephyr SO, and Zephyr ST list assisted settings up to 28 mph. Each ships set to 20 mph, and the higher setting requires an authorized display change where local rules permit.
Yes. At 28 mph, stopping distance, surface changes, traffic, and rider visibility require more attention than they do at a casual cycling pace. Use a speed that fits the route, conditions, and local rules.
Usually. Higher assisted speed asks the motor for more energy, and hills, wind, load, temperature, tire pressure, and frequent acceleration add to that demand. Plan range from your real route rather than the largest published estimate.
No. The models in this collection list assisted settings up to 28 mph, subject to the permitted configuration and local rules.
No single rule covers every state, path, street, or trail. Check current state and local requirements plus the rules for the route you plan to use before changing the factory setting.
