Design & Build Quality
The S1F feels built for real commuting. The frame is solid at city speeds, and the deck gives enough room to move your stance. The stem is thick and resists flex under normal braking, so steering stays calm when the road gets choppy. The deck grip is rubberized, and it cleans fast with a damp cloth.
Cables sit in channels with grommets, so snag points stay low. The hinge uses a simple latch with a secondary catch, and it folds fast on a train platform. The latch closes with a clean snap, and it does not rattle in normal use. Paint stands up to bag straps and casual scuffs. Deep metal contact will still mark it, so a strip of protective tape on the sides helps.
The deck is long for a commuter, and that length makes it easy to stagger your feet and shift weight over bumps. You get space for a wider stance in turns, so control stays steady at mid-speeds. The kickstand lifts the rear wheel a touch on uneven ground, and that keeps the scooter from rolling when parked nose-down.
Motor, Power & Acceleration
The rear hub is rated at 500 W and peaks near 1,000 W. That gives brisk launches in Sport mode and steady pull in Drive. Takeoff feels smooth, and there is no harsh surge when you roll on the throttle. So you can meter speed in crowded lanes without jerky inputs. Low-speed control is easy, and that helps when you weave around strollers near park gates.
At 10 to 15 mph, the S1F rides quiet. Motor whine fades behind tire noise on rough asphalt, and the controller maps power in a way that keeps traction on damp paint lines. If you hold a steady wrist, cruise control locks speed after a short hold. Then your right hand can relax on longer straight runs.
Hill starts on moderate grades feel fine. On an 8% climb from a dead stop, the scooter takes a beat, then builds speed and holds a pace you can live with. Heavier riders will see a slower rise, but grip stays clean if tire pressures are in range. Weight shifts back under throttle, so traction improves on wet leaves.
Battery, Range & Efficiency
The 675 Wh pack is the star, and it gives real headroom for mixed commutes. Published range numbers assume light wind, modest speed, and a light rider. City life rarely matches that, so plan for less on cold days with stops and fast segments. With an easy wrist and a 15 to 18 mph target, many riders can finish a long round trip without a top-off. Push near top speed for long stretches, and range will drop as expected.
Energy use stays even across modes if you ride steady, and regen adds a bit back on rolling descents. You can raise or lower recovery in the app, and that lets you tune feel. In dense traffic, a medium setting works well and keeps the lever light. On long downhill sections, a higher setting takes work off the front drum and keeps speed in check.
Cold weather cuts range, so leave with a warm pack when you can. Then store the scooter inside after rides. Keep it near half charge for longer gaps, and give yourself buffer on windy days. That plan keeps frustration low and battery life high.
Ride Quality, Handling & Comfort
The S1F rolls on 10 x 2.5 in tubeless pneumatic tires with spring suspension at both ends. This combo smooths broken asphalt and pavers better than many peers, and it keeps the deck stable through long bends. The stem resists head shake at 18 to 20 mph, so confidence stays high for newer riders. Tire pressure matters here, so start near 35 psi front and 38 psi rear for a 180 lb rider. Then move a few psi up or down until steering feels light but planted.
The bars sit high enough for riders near 5’11” to stand tall, and shorter riders can still reach with bent arms and relaxed shoulders. Grips are firm, not squishy, so they do not twist under load. That helps with precise counter-steering when you dodge a pothole late. The chassis is quiet. You may hear a light rattle from the rear fender on brick, and a small rubber bumper can mute that fast.
Curbs and speed cushions need a slow, square approach. This is not a jump toy. So ride it like a road bike with fat tires, and roll rough patches with bent knees. That habit keeps stress off the latch, bearings, and your ankles.
Braking & Safety Features
The front drum does the heavy work, and it gives strong, linear bite with little hand effort. The rear electronic brake adds drag and lights the tail, so following traffic sees your intent sooner. Set regen to medium if you want a smooth roll-off feel. Then close the throttle and let it add gentle drag before you touch the lever.
Lighting is a clear step up. The headlight throws a usable beam at urban speeds, and the tail lights brighten under brake. Deck LEDs make your outline pop from the side, and turn signals front and rear show intent at night. So lane changes feel safer on multi-use paths. Bright sun can wash small lenses, so use hand signals during the day.
Water resistance is strong for a commuter. The body holds an IP55 rating, and the controller and battery sit at higher protection. That helps on wet mornings and light rain. It is still smart to avoid standing water that reaches the hub center, and bearings will last longer if you keep puddles shallow.
Portability & Daily Usability
At 52.9 lb, the S1F is not light. You can carry it up one flight with a short rest at the top, but for three floors, use the elevator. The folded length is long, so check trunk depth on compact cars. It fits diagonally in many hatchbacks without drama, and the latch is quick. The safety catch stops accidental openings when you lift by the stem.
Daily tasks are easy. The center display reads at a glance in sun, and the kickstand is stable on soft tarmac. The rear fender keeps spray off your back, and the charging ports sit high enough to avoid splash. Caps close tight, so grit stays out. The bell is loud enough for shared paths, and the brake light draws eyes early in the evening.
If you mix rail with your ride, the one-hand roll to the platform helps. Grip the stem near the clamp, then keep the front wheel light. Guide it like a slim suitcase for short pushes, and watch for gaps at platform edges.
Features, App & Extras
INMOTION’s app is clean, and pairing is fast. You can set a speed cap and choose regen strength. You can lock the motor for short café stops, and you can tune deck lighting to match your taste. Firmware updates arrive over the air, so fixes and refinements come without a shop visit.
Cruise control kicks in after you hold a steady speed for a few seconds, and it cancels the instant you pull the brake. That makes sense on crowded lanes. The display shows battery bars, speed, and mode. It is simple, bright, and quick to read. Some regional builds add a USB-A port that can trickle a small light if needed. Check your batch label to confirm.
The deck LEDs are not just flair. They make your side profile visible at dusk, and they add a clear boundary in traffic. Pick a calm color for late rides, and pair that with a reflective strap on your bag for extra side visibility.
Charging Experience & Maintenance
Standard charging takes about seven hours from low, and two chargers cut that time in half. So all-day riders can top off at lunch and finish strong. The pack prefers room-temperature charging, so bring the scooter inside before you plug in during winter.
Maintenance is simple. Drum brakes need little care beyond cable tension checks, and regen reduces wear. The tires are tubeless, which lowers pinch-flat risk. Carry a plug kit and a mini pump, and you can seal small punctures in minutes. Keep the hinge bolts snug, wipe the deck and stem after wet rides, and check the sidewalls for cuts every few weeks if your route includes gravel.
Do you need to replace the brake shoes each season? Not for most riders. City use with mixed regen can stretch service past a year, and lever feel stays steady with small barrel tweaks. If the pull grows long, adjust at the barrel and plan a swap.
Who the INMOTION S1F Is For
Pick the S1F if range and weather resistance sit high on your list. Long bike-lane commutes, campus loops, and cross-town errands fit it well. Heavier riders benefit from the torque and the higher pack voltage, and new riders get a gentle throttle map with stable steering. Riders in damp climates get peace of mind from the sealed electronics, and the lighting package helps at night.
Skip it if you climb many stairs each day. Weight adds up fast when you carry more than a floor or two. Choose a lighter scooter, like the INMOTION Air Pro, if your storage spot has no ramp or elevator. If you want wild top speed, look elsewhere, and focus on sport models instead. This is a fast commuter, not a drag racer.
Value for Money & Verdict: INMOTION S1F review
You get the S1F for its battery, water protection, steady brakes, and strong lighting. You keep it for the low-drama ownership. The chassis rides quiet, the latch is quick, and the app features cover daily needs. Some riders will want hydraulic brakes or an even lighter frame, but that lives in a different class and price bracket.
This package hits a nice sweet spot for long urban rides. It blends comfort, safety features, and range in a way that serves real commuters. The finish feels mature, the controls are friendly, and the lighting stands above most peers. So if your route is long and varied, the S1F makes a strong case to be your daily ride.
