Mokwheel FLINT PRO ST Review: A Light 35-Pound Belt-Drive Commuter for $1,600
Mokwheel's belt-drive city bike stays light and nearly maintenance-free, and its small battery makes it a better fit for everyday commutes than for chasing the 70-mile claim.

What the stars are rated against
The stars compare this bike with other commuter e-bikes we have scored — 49 of them, priced $1,120–$2,080. They are a ranking inside that group, not an absolute grade: four stars means it beats most of that set on the measure, not that it hits some fixed standard.
Peers are drawn from a tight price band around this bike, so a $1,000 commuter is judged against other $1,000 commuters rather than against machines costing three times as much. Change the group and the stars would change with it.
The headline Genius Score is not decided by that group alone. It blends the category ranking above with a market-wide view across every bike we publish, so a bike cannot climb simply by sitting in a weak category. How we score.
Most e-bikes are a hassle to move when the battery's dead or you need to bring them inside. The Mokwheel Flint Pro ST isn't. At 35 pounds it's one of the lightest e-bikes out there, so hauling it up to a walk-up apartment or lifting it onto a car rack is something you can actually do on your own. The belt drive backs that up: no oiling, no chain grease, nothing to fuss over week to week.
It earns a 68 out of 100 Genius Score, which puts it in solid value territory for a mid-priced commuter. It's a e-bike, meaning only, no , with help up to 20 mph. The trade-off for all that lightness is a small battery and a modest motor, so it's happiest on flatter, shorter rides.
Pros & cons
What we like
- At 35 pounds, it's light enough to carry up a flight of stairs or lift onto a rack without help, which is rare for an e-bike.
- The single-speed belt drive means no chain to oil and no derailleur to fuss with, so upkeep is close to nothing.
- TEKTRO HD-M275 give strong, low-effort stopping in city traffic and wet weather.
- It carries up to 300 pounds, so a rider plus a loaded backpack or panniers is no problem for the .
- At $1,599.99, it's a lot of low-maintenance commuter for the money.
Worth weighing
- There's only one gear, so when the road tilts up you've got nothing easier to shift into, and the 250W motor's leaves your legs doing a big share of the climbing.
- The narrow 700×45C tires keep it quick on pavement but out of their depth on gravel, broken roads, or curbs.
Key specs
The motor & power
The Flint Pro ST runs a 250W , with steady and a peak. That's modest by e-bike standards, so the help builds gently instead of launching you off the line.
With and a single gear, it has enough pull to get you and a bag of groceries moving on flats and gentle rises. Steep hills are where it works hardest, because there are no lower gears to drop into, so you'll be putting in real effort alongside the motor.
As a bike, it's only with no , and the help cuts out at 20 mph. You have to pedal to get any assist, but Class 1 also opens up the most places to ride, including bike lanes and many trails where throttle bikes aren't welcome.
If you're comparing spec sheets, you may spot 750W and 1,300W figures floating around Mokwheel's lineup. Those belong to a bigger, heavier model, not this one. The Flint Pro ST is a 250W motor with a 500W peak, so judge it on that.
Range & battery
The battery is a 360Wh (36V, 10Ah), which is on the small side for a commuter. Mokwheel lists , and like every manufacturer's top number, that figure assumes flat ground, light effort on the lowest assist, and ideal conditions.
Real riding rarely matches the brochure. On hillier routes, in colder weather, or with the assist turned up, count on noticeably fewer miles per charge. For a daily commute in the 10-to-15-mile round-trip range, that likely means charging every few days, not nightly.
Ride & components
This is a road-style commuter, not a fat-tire cruiser. The CST 700×45C tires are fairly narrow and roll fast on pavement, so they're happiest on smooth city streets and paved paths.
The 35-pound frame is the headline. Most e-bikes land between 50 and 70 pounds, so being able to lift this one with one hand changes what you can do with it. You can carry it inside, wedge it into a cramped apartment, or set it on a rack without recruiting a friend.
Stopping comes from TEKTRO HD-M275 , which stay consistent and easy to pull even in the rain. The single-speed belt drive keeps the whole thing quiet and clean, so there's no chain grease on your pant leg and nothing to shift.
Despite the light frame, it's rated to haul 300 pounds, so a heavier rider or a full week's groceries stays well within the .
Price & value
At $1,599.99, the Flint Pro ST sits right in the middle of the commuter market, and for that price you get hydraulic brakes, a maintenance-free belt drive, and a genuinely light frame.
That mix is where the value shows up, since it's priced well for what it delivers. Just be clear about what you're buying: a light, low-fuss city bike for short, flat rides, not a long-range hill-climber.
Who it's for
The walk-up apartment rider
If you live up a flight or two of stairs, or you have to stash your bike in a tight apartment or an office corner, the 35-pound frame is the whole reason to buy this. You can bring it inside without dreading it, which is something most e-bikes just can't offer.
The flat-city errand runner
If your riding is mostly short commutes and errands over flat streets, the belt drive and make this a grab-and-go bike. Nothing to oil, nothing to shift, and it stops well in traffic and rain.
The hill-country commuter
If your commute is genuinely hilly, this probably isn't the one. The single-speed drive and light-duty motor are tuned for flat ground, so long grades will have you working hard. Riders facing real elevation are better off with gears or a stronger motor.
The rider who'd rather not pedal
If you were counting on a to cruise without pedaling, whether up a hill or away from a stoplight, this isn't it. The Flint Pro ST is only, so you're always turning the cranks and the motor just makes it easier.
Frequently asked
Does the Mokwheel FLINT PRO ST have a throttle?
No. It's a -free, bike, so you have to pedal to get the motor's help. The assist runs up to 20 mph.
How far can the Mokwheel FLINT PRO ST go on a charge?
Mokwheel claims up to 70 miles, but that's a best-case number from a small 360Wh . On real commutes with hills and higher assist, plan for meaningfully less.
Can you ride the Mokwheel FLINT PRO ST without pedaling?
No. There's no throttle, so the motor only kicks in while you're pedaling. Stop pedaling and the assist stops too.
What class is the Mokwheel FLINT PRO ST?
It's a e-bike: pedal-assist only, no throttle, with motor help up to 20 mph. Class 1 bikes are allowed in the most places, including many bike paths and trails.
How much does the Mokwheel FLINT PRO ST weigh?
35 pounds, which is unusually light for an e-bike and easy to carry or lift onto a rack.
Does the Mokwheel FLINT PRO ST have gears?
No, it uses a single-speed belt drive. That keeps maintenance low, but it also means there's no lower gear for steep climbs.
How it compares to its siblings
The PRO ST costs $200 more than the FLINT and FLINT ST while scoring lower on Genius (68 vs 77) and running a less powerful motor (250W/500W vs 350W/550W); what that extra money buys is a single-speed belt drive instead of an 8-speed chain, trading gearing options for lower maintenance. Against its direct sibling, the FLINT PRO, it's 4 lb heavier (35 lb vs 31 lb) and has 50 lb less payload capacity (300 lb vs 350 lb) for the same price. If you want the belt drive, get the FLINT PRO instead; if you don't need it, the base FLINT is cheaper and scores better.

Guides worth reading
- Nominal vs peak watts on an e-bikeThe wattage in the headline is usually the peak figure, which can be roughly double the number the motor actually sustains.
- E-bike range explainedEvery range figure on every spec sheet is a best case. Here is how to translate it into what you'll really see.
- Mid-drive vs hub motorWhere the motor sits changes how the bike climbs, what it costs, and what wears out. Neither is better everywhere.
How we score: the Genius Score blends a bike's capability against same-price peers with its value for the money, weighted for what this commuter buyer prioritises.
