Types of e-bikes: which one fits how you ride

“The simple believes everything, but the prudent gives thought to his steps.” Proverbs 14:15 (ESV)

The class tells you how fast the motor helps (classes explained). The type tells you what the bike is built to do. Pick the wrong type and good specs won’t save it. A 77 lb fat tire bike is a pain in a third-floor walk-up. A small-wheeled folder feels skittish on a rutted gravel road.

Below are the six main types, with the numbers from bikes I’ve tested where I have them.

The comparison table

The weights come from my reviews and the makers’ published specs. The Ramblas ADV (the Ramblas’s successor) is 54 lb per Aventon, the RadWagon 4 about 77 lb, and the Aventure 3 76 lbs per Aventon.

Commuter

Commuters are built for pavement. You get medium-width tires with a smooth tread, usually fenders and lights, and often a rear rack. Most are Class 2 or Class 3. A good commuter is lighter than the other types here, which matters when you’re lifting it onto a curb, into a car or up stairs.

I’ve tested two:

• Aventon Pace 500.3: Aventon Canada lists it as Class 2; the 28 mph figure comes from its page’s top-speed claim, and its FAQ caps the throttle at 20 mph. It’s listed as discontinued.
• Aventon Soltera 2: a city bike that tops out at 20 mph with a 350 W motor, listed at $1,199.

What to check when you shop:

• Fenders and a rack that come with the bike. Adding them later costs extra and they often fit worse.
• Integrated lights that run off the main battery.
• A removable battery if you can’t park next to an outlet.
• Hydraulic disc brakes if your route has big hills.

Skip it if most of your riding is gravel, sand or snow.

Fat tire

Fat tire bikes use tires about 4 inches wide. They grip on sand, snow and loose gravel, and the big air volume works as extra suspension. They’re also the most popular type I review on the channel.

The tradeoffs are weight and efficiency. Every fat tire bike I’ve weighed or looked up falls between 73 and 77 lb, and wide tires take more effort to roll on pavement, which cuts into range. Even so, on my first-gen Aventure I got 41 miles on PAS 5 over a mix of hills and off-road.

The four I’ve tested split into two groups:

• Hub drive, 28 mph capable: the Aventure 3 ($1,999 at review time), which Aventon lists as Class 2 with a top speed of “20MPH (Adjustable to 28)”, and the Mokwheel Obsidian. The Obsidian has full suspension, which helps a lot on washboard roads.
• Mid-drive, Class 1: the Aventure M ($2,899 list). It climbs better and feels more natural to pedal, and it costs more.

There’s a longer breakdown in best fat tire e-bike.

What to check when you shop:

• Tire pressure range. Running lower pressure on sand makes a huge difference.
• Whether a rack and fenders come with the bike.
• Where you’ll park it. These bikes are wide and heavy.

Skip it if you need to lift the bike often or you ride only on smooth pavement.

Cargo

Cargo bikes carry kids, groceries or work gear, either on a long rear deck (a longtail) or in a front box. Almost all are Class 2, because a throttle makes loaded starts so much easier. These are the bikes most likely to actually replace car trips.

• Aventon Abound: 440 lb total payload with a 143 lb rated rear rack. It was $2,200 at review time, and close to $3,000 once I added accessories.
• RadWagon 4: 350 lb total payload with a 120 lb rear rack. It’s listed at $1,299, but it’s out of stock as of October 2026.
• MOD Easy SideCar: puts a passenger beside you in a sidecar instead of behind you. MOD lists it at $3,899.

What to check when you shop:

• Total payload compared with you plus your heaviest load.
• Rear rack rating, separate from total payload.
• The passenger accessories you’ll actually need, such as a seat pad, running boards and a rear enclosure. Price them in from the start.
• A kickstand that holds the bike steady while kids climb on.
• A ground-level place to park it. These bikes are long.

Skip it if you have no ground-floor storage or you rarely carry more than a backpack.

Folding

Folding e-bikes hinge at the frame and usually the handlebar stem, so they fit in a car trunk, under a desk or on a train. To make them small, makers use 16 to 20 inch wheels. Smaller wheels turn quickly, which feels twitchy at speed and harsher over potholes.

What to check when you shop:

• Folded size and weight. A folder you can’t lift into your trunk fails at its one job.
• Whether the fold latches feel solid with no play.
• Where the battery sits, and whether you can charge it with the battery out of the bike.

Good for: RVs, boats, apartments, and commutes that include a train or bus. Skip it if your rides are long, fast or rough.

Mountain (eMTB)

Electric mountain bikes have trail geometry, real suspension and knobby tires. The good ones use a mid-drive with a torque sensor, so the assist matches how hard you pedal and technical climbs feel controlled instead of jerky.

The Aventon Ramblas is the one I’ve tested. It’s a Class 1 hardtail with the A100 mid-drive and Maxxis Rekon 29 x 2.4 tires. Aventon doesn’t list the original’s other specs anymore; its successor, the Ramblas ADV, lists 100 Nm, a 708 Wh battery and 54 lb. Class 1 matters here, because it’s the class trail managers most often allow. Several of the state laws I checked, including Washington, Minnesota, Maryland, Virginia and Texas, let local governments or land agencies set their own rules for paths and trails. So check the rules for the trail system, not just the state.

Skip it if you ride only on pavement. You’d be paying for suspension you won’t use.

Moped-style

Moped-style bikes look like small motorcycles, with a long bench seat, fat tires and often foot pegs. They’re popular with teens. Most states define an e-bike as having working pedals and a motor of 750 W or less, with assist cutting out at 20 or 28 mph (Michigan’s definition is typical). Plenty of moped-style bikes sold online go past those limits. If a bike doesn’t fit a class, it may legally be a moped or a motor vehicle, with the licensing and registration that comes with that.

What to check when you shop:

• A class sticker on the frame. Several states require one, including Arizona, Florida, Ohio and Virginia.
• The real motor rating and top speed, not “up to” marketing numbers.
• Whether the pedals are actually usable.

Skip it if you want to pedal for exercise, or if it’s for a rider too young for a license. See the parents’ guide.

How to pick

1. Name the ride you’ll do most often, not the one you’ll do once.
2. Pick the type from the table above.
3. Pick the class from classes explained and your state’s rules.
4. Check the weight against where you’ll store the bike.
5. Then compare specs. My reviews list tested range wherever I measured it.
