Macfox X1S, X7/X7L, X2 Pro, and M16 each have a listed top speed of 20 mph. The meaningful difference is not which model reaches a higher number. Motor output, battery capacity, tire size, suspension, brakes, rider fit, and route all change how an e-bike reaches and holds that speed.
If you are comparing electric bikes, start with your route and fit instead of choosing by top speed alone.
Macfox Top Speed Comparison at a Glance
All four models below are presented as Class 2 e-bikes with a thumb throttle and a 20 mph top speed. Their power, range, tires, suspension, braking setup, and rider fit are different.

|---|---|---|---|---|---|
| Macfox X1S commuter e-bike | 20 mph | 500W rated / 750W peak | 500Wh; up to 28 miles with one battery or 56 miles with two | 20 × 4.0 in. tires, front suspension, hydraulic disc brakes, 220 lb payload | Daily commuting, errands, and neighborhood riding |
| Macfox X7/X7L fat-tire e-bike | 20 mph | 500W rated / 750W peak | 624Wh; up to 35 miles with one battery or 70 miles with two | Extra-wide tires, front suspension, hydraulic disc brakes, 330 lb payload | Riders prioritizing stability, load capacity, and mixed surfaces |
| Macfox X2 Pro electric mountain bike | 20 mph | 750W rated / 1000W peak; 65 Nm | 960Wh; up to 40 miles with one battery or 80 miles with two | Extra-wide tires, front and rear suspension, hydraulic disc brakes, 330 lb payload | Longer rides, uneven surfaces, hills, and heavier loads |
| Macfox M16 electric bike | 20 mph | 500W rated / 750W peak | 499Wh; up to 25 miles | 16 × 4.0 in. tires, front suspension, mechanical disc brakes, 220 lb payload | Smaller riders who need the most compact fit in the lineup |
Why the Same 20 MPH Top Speed Can Feel Different
Top speed and motor output answer different questions. A configured speed limit determines when motor assistance stops adding power. Motor output affects how the bike accelerates, responds on a hill, and handles a heavier combined rider-and-cargo load. That is why the X2 Pro can feel stronger under load without having a higher listed top speed than the X1S, X7, or M16.
Battery capacity affects how much ride you have available, not a guaranteed higher speed. The larger battery and dual-battery options are more relevant to route length and charging frequency than to choosing the fastest Macfox model.
Tires and suspension change control and comfort. The X1S balances fat-tire stability with a city-focused setup. The X7/X7L adds extra-wide tires and higher load capacity for a more planted feel. The X2 Pro combines extra-wide tires with front and rear suspension for uneven routes. The M16 uses a smaller wheel and frame package for riders who need a more compact fit.
Choose a Macfox Model by Route and Rider Fit
Choose X1S for everyday commuting
The X1S is the straightforward choice for repeated city trips, errands, and neighborhood routes. It has the same 20 mph listed top speed as the other models, so its advantage is a commuter-focused balance rather than a higher speed claim.
Choose X7 or X7L for stability and load capacity
The X7 family suits riders who want a planted fat-tire ride, a 330 lb payload rating, and two frame-fit options. Choose between X7 and X7L by rider fit; top speed is not the deciding difference.
Choose X2 Pro for longer or rougher routes
The X2 Pro combines the largest battery, the highest motor output in this group, extra-wide tires, and front and rear suspension. That package supports longer rides, hills, uneven surfaces, and heavier loads while keeping the same listed 20 mph top speed.
Choose M16 for the most compact fit
The M16 uses 16-inch fat tires and a lower seat height than the larger models. Rider age, helmet requirements, and permitted riding locations still depend on state and local rules, so fit alone does not determine where someone may ride.
Compare the complete lineup and current configurations before buying through Macfox's electric bike models.
What Changes Real-World E-Bike Speed?
A listed top speed is a controlled specification, not a promise that every rider will see the same number in every condition. Hills, rider and cargo load, wind, temperature, battery charge, tire pressure, surface, stop-and-go traffic, and brake drag can change acceleration and the ability to maintain pace.
Use the guide to how fast electric bikes go for the broader relationship among class, power, and riding conditions. For market-wide speed claims outside the normal class system, see the guide to fastest electric bikes.
If a bike no longer reaches its normal performance, start with tire pressure, brake drag, battery condition, load, and maintenance. The guide to restore normal e-bike speed safely focuses on diagnosis rather than removing built-in limits.
Top Speed, Class, and Local Rules
Macfox X1S, X7/X7L, X2 Pro, and M16 are presented as Class 2 models with a 20 mph top speed and thumb throttle. That label is a starting point, not permission to ride on every road, bike lane, path, trail, park, or campus.
Use the electric bike class guide to compare control types and assisted-speed cutoffs. Then check the guide to U.S. e-bike speed limits and confirm the current rule for the exact route and local authority.
Macfox Top Speed FAQs
What is the Macfox X1S top speed?
The Macfox X1S has a listed top speed of 20 mph. Its 500W rated motor and 750W peak output support acceleration and everyday commuting rather than a higher configured speed.
What is the Macfox X7 top speed?
The Macfox X7 and X7L have a listed top speed of 20 mph. Choose between them by rider fit, and choose the X7 family for its extra-wide tires, stability-focused ride, and 330 lb payload rating.
What is the Macfox X2 Pro top speed?
The Macfox X2 Pro has a listed top speed of 20 mph. Its 750W rated motor, 1000W peak output, 65 Nm of torque, larger battery, and front and rear suspension are advantages for hills, loads, and uneven routes—not evidence of a higher listed top speed.
What is the Macfox M16 top speed?
The Macfox M16 has a listed top speed of 20 mph. Its main distinction is compact rider fit, not a different speed setting.
Should I remove a speed limiter?
Do not treat limit removal as a routine performance upgrade. Changes to the controller or electronic system can affect classification, route access, braking demands, heat, reliability, and warranty support. Diagnose lost performance and use the bike within its intended configuration and local rules.
