What the stars are rated against
The stars compare this bike with other commuter e-bikes we have scored — 18 of them, priced $1,959–$3,639. 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.
What you're really paying for with the Biktrix Swift CVT 2 is a daily ride that stays quiet and clean. It runs a carbon belt instead of a chain, so there's no grease to wipe off your pant leg, and the motor feeds its power through a stepless Enviolo hub. It's the kind of low-fuss setup that a lot of commuters happily pay extra for.
Underneath that easy experience is a genuinely strong 500W Bafang motor with , which is a lot of pulling power for a commuter, and it's tuned for speeds, so carries you up to 28 mph. The honest catch is value: at $2,799 you're paying a premium, and some competitors give you the same speed and hill power for a smaller outlay.
Pros & cons
What we like
- The Enviolo CVT hub and carbon belt skip chain cleaning entirely and let you pick any gear you want, which is the whole reason to buy this bike.
- The motor's handles steep grades even with a loaded rack.
- A 720Wh backs an estimated 55 miles of range, plenty for a week of short round-trip commutes between charges.
- tuning means up to 28 mph, so you can keep pace with city traffic.
- on 180mm rotors give confident, low-effort stopping.
Worth weighing
- Value is the soft spot: $2,799 buys a lot of commuter, but you can find comparable range and power elsewhere for less.
- Biktrix doesn't publish a , so heavier riders or anyone hauling cargo is left guessing about the limit.
Key specs
The motor & power
The heart of this bike is a 500W Bafang M430 motor, and mid-drives earn their keep on hills. Because the motor pushes power through the same gears you pedal, it multiplies its effort as you climb instead of just brute-forcing its way up.
That's backed by , a big number even for a mid-drive. What it buys you is the ability to pull away from a stop on a steep incline, or carry a full load of groceries up a bridge ramp, without the motor bogging down.
It's tuned for speeds, so will push you to 28 mph, quick enough to hold your own on a busy road. Biktrix doesn't publish a figure, so judge the motor on that steady 500W and the strong torque.
Range & battery
The standard 720Wh is rated for about 55 miles per charge. That's an ideal-conditions estimate, so on hilly routes, in cold weather, or under a heavy load, plan on landing somewhere below it.
Even a conservative real-world figure covers most commutes with room to spare, which means you can go several days between plug-ins if your daily ride is on the shorter side.
Biktrix lists more than one battery on the same page. The Swift CVT 2 ships with the 720Wh pack that gets you the 55-mile estimate, but there's a larger 1008Wh upgrade rated up to about 70 miles if you want more cushion. Ignore the stray '520Wh' you may spot on the page; that's just a generic example in their spec explainer, not this bike's battery.
Ride & components
The star here is the Enviolo CVT hub paired with a carbon belt drive. Instead of clicking through fixed gears, you twist the grip to dial in any ratio you want across a wide range, and you can do it while stopped, which is a small luxury that pays off at every red light.
The belt takes the place of a greasy chain, so there's nothing to oil and nothing to stain your clothes. It's the kind of setup that stays quiet and clean for years with almost no attention.
Stopping comes from Star Union dual-piston on 180mm rotors, which give you firm, one-finger braking even at Class 3 speeds. The bike rolls on street tires sized to the frame, 26x2.2 inches on the medium and 29x2.3 on the large, so it's set up for pavement rather than trails.
At about 68 pounds it's normal weight for a commuter carrying a battery and a beefy belt-drive hub, so it's a solid, substantial bike to ride and a two-person job if you need to carry it up a flight of stairs.
Price & value
At $2,799 the Swift CVT 2 sits firmly in premium commuter territory, and our Genius Score lands at 64 out of 100. The number is held back by value, because on the numbers alone, cheaper commuters keep pace on range and climbing.
What that math misses is the drivetrain. The Enviolo CVT and carbon belt are genuinely nicer to live with than a standard chain-and-derailleur setup, and they cost real money to build. If low maintenance and smooth, shift-anywhere gearing matter to you, the premium makes sense; if you're shopping mainly on range and power per dollar, you can do better.
Who it's for
The set-it-and-forget-it commuter
If you're tired of degreasing a chain and babying a derailleur, this is an easy call. The carbon belt needs almost no upkeep, and the stepless hub means there's no fussing with gear indexing over time.
The hill-heavy commute
If your ride home involves real climbs or a bridge, the motor has the to keep you moving up grades, and you can spin down to an easy ratio without breaking stride.
The budget-minded buyer
If your main filter is miles and power per dollar, look hard before you commit. At $2,799 you're paying for the belt-and-CVT experience, and other bikes cover the same miles and grades for less if that drivetrain isn't your priority.
The no-pedal cruiser
If you specifically want to sit back and ride on a without pedaling, this may not be your bike. It's built around up to 28 mph, and Biktrix's spec listing doesn't confirm a throttle, so don't count on one.
Frequently asked
How far does the Biktrix Swift CVT 2 go on a charge?
Biktrix estimates about 55 miles from the standard 720Wh battery. Real-world range runs lower on hills, in the cold, or under a heavy load, and there's a larger 1008Wh option rated up to roughly 70 miles.
How fast does the Biktrix Swift CVT 2 go?
It's rated for speeds, so takes you up to 28 mph.
What class is the Biktrix Swift CVT 2?
It's a Class 3 e-bike, meaning pedal-assist support up to 28 mph.
Does the Biktrix Swift CVT 2 have a throttle?
Biktrix's class listing doesn't confirm a , so we can't say for certain. What's clear is that it's tuned for Class 3 pedal-assist up to 28 mph.
How much does the Biktrix Swift CVT 2 weigh?
About 68 pounds with the battery installed, which is normal for a commuter carrying a mid-drive motor and a belt-drive hub.
How much does the Biktrix Swift CVT 2 cost?

How it compares to its siblings
The Swift CVT 2 is the lighter of the two at 68.1 lb, versus 71.8 lb for the SwapTop CVT, and it comes with slightly less torque at 120 Nm against the SwapTop's 130 Nm. Price, battery (720 Wh), claimed range (55 mi), Class 3 status, and brakes are identical between the two, so this comes down to weight versus torque and tire fit. It also runs different tire sizing (26x2.2 on the M frame, 29x2.3 on the L) rather than the SwapTop's 26-inch hybrid tire, which matters more for fit than performance. If you don't need the extra torque or the SwapTop's stated 330 lb payload rating, the few pounds you save here are the only real reason to pick this one over its sibling.
