Zero Fxs
The Zero Fxs has a top speed of 137 km/h, produces 46 hp (34 kW) — note: varies slightly by model year and weighs 132 kg. Motoryk rates it 7.5/10.
The Zero FXS was introduced by Zero Motorcycles around 2016 as a supermoto-styled variant of the FX platform, designed for urban commuting and light off-road use. It features a lightweight aluminum frame, street-legal supermoto tires, and Zero's Z-Force motor, positioning it as a nimble city bike with off-road DNA. It became notable for its combination of low weight, instant electric torque, and versatility, appealing to urban riders seeking a practical yet exciting electric motorcycle.

What Buyers Should Know
Battery Longevity Matters
The Z-Force lithium battery is rated for hundreds of charge cycles but can degrade faster with frequent DC fast charging. Always check battery health percentage on used models — replacement costs can exceed $3,000.
Near-Zero Maintenance
With no oil changes, no clutch, and no transmission, annual maintenance costs are dramatically lower than gas bikes. The main recurring service is belt inspection and brake fluid changes.
Steep Depreciation Curve
Zero FXS models depreciate significantly in the first 2-3 years, meaning used buyers get strong value — but reselling later can be challenging as newer, higher-range models flood the market.
Generations & Specs by Year
Introduced as supermoto variant of FX; 34hp motor, 223kg equivalent torque, smaller battery pack.
Updated ZF7.2 and ZF3.6 battery options, improved power pack modularity, refined chassis geometry and braking.
Cypher III OS introduced, improved torque curve, updated motor controller, enhanced regenerative braking settings.
Cypher III+ OS, revised suspension tuning, updated display interface, improved charge port and battery management.
Used Buyer Review
"Urban riding reimagined, but range limitations demand honest self-assessment first."
$5,000-$9,500 usedThe Zero FXS is genuinely brilliant if you ride it for what it is — a lightweight, torquey urban shredder that'll embarrass sportbikes off the line in city traffic. That instant torque delivery is addictive in a way internal combustion simply can't replicate, and the chassis is taut and flickable enough that twisty backroads are actually enjoyable. For commuting and weekend blasts under 50 miles, it's close to perfect. Buying used, you need to do your homework. Battery degradation is the real concern — ask for charge cycle history and check the BMS data through the Zero app before handing over cash. Bikes from 2019 onward with the Z-Force 3.6 pack are significantly more usable. Check charging port condition obsessively; replacements aren't cheap and dealers are thin on the ground outside major cities. Range anxiety is real and not entirely overblown. The 3.6kWh tank version barely scrapes 40 miles spiritedly ridden. Budget the optional Power Tank if you find one without it — your sanity depends on it.
