How to Choose an Electric Bike

How to Choose an Electric Bike — Complete Guide to Motors, Batteries & Frame Styles

Electric bikes are changing how people commute, exercise, and explore. But with hub motors vs mid-drive, battery ranges, and different classes, it's easy to feel overwhelmed.

This guide covers everything you need to know — so you buy the right e-bike the first time.

Step 1 — E-Bike Classes (Legal in the US)



Class Motor Throttle Speed Limit Where Allowed
Class 1 Pedal-assist only No 20 mph Most bike paths, trails
Class 2 Pedal-assist + throttle Yes 20 mph Most bike paths
Class 3 Pedal-assist only No 28 mph Roads, bike lanes (not all trails)

What you need to know:

  • Class 1 and 2 are legal on most bike paths and trails

  • Class 3 is restricted on some paths (check local laws)

  • No license, registration, or insurance required for any class (in most states)

  • Helmets: Required for Class 3 in many states, recommended for all

What we sell: Class 2 and Class 3 e-bikes.

Step 2 — Motor Types: Hub Drive vs Mid-Drive



Feature Hub Drive (Rear or Front) Mid-Drive
Motor location Inside wheel hub At pedals (bottom bracket)
Feel Pushes from wheel Natural, like strong legs
Hill climbing Good Excellent
Efficiency Less efficient on hills Most efficient
Maintenance Simple More complex
Price Lower Higher
Best for Flat commutes, casual riding Hills, off-road, heavy loads

Recommendations:

  • Flat city commuting: Hub drive is fine, saves money

  • Hilly areas or off-road: Mid-drive is worth the extra cost

  • Heavy rider or cargo: Mid-drive handles weight better

What we sell: Both hub drive and mid-drive options available.

Step 3 — Motor Power (Watts)



Wattage Speed Hill Climbing Legal Best For
250W 15-18 mph Light hills Legal everywhere Flat commutes, casual
350-500W 18-22 mph Moderate hills Legal in US (Class 1-2) Most commuters
750W 22-26 mph Steep hills Legal in US (Class 2-3) Heavy riders, hills
1000W+ 28+ mph Very steep May require license Off-road only

Important: Higher watts ≠ always better. 500-750W is perfect for most riders. More power means heavier bike and shorter battery range.

Step 4 — Battery Range (How Far You Can Go)

Battery range depends on:

  • Rider weight

  • Terrain (hills drain faster)

  • Assist level (Turbo uses more than Eco)

  • Tire pressure

  • Wind

Realistic range estimates:



Battery Size Eco mode (low assist) Turbo mode (max assist)
36V 10Ah (360Wh) 20-30 miles 10-15 miles
48V 10Ah (480Wh) 30-45 miles 15-25 miles
48V 14Ah (672Wh) 40-60 miles 20-35 miles
48V 20Ah (960Wh) 60-80 miles 30-50 miles

What you need:

  • Commute under 10 miles round trip → 360-480Wh is fine

  • Commute 10-20 miles → 480-672Wh recommended

  • Long rides or heavy rider → 672-960Wh

Charging time: 3-6 hours from empty. Removable batteries (can charge indoors) are convenient.

What we sell: Bikes with 480Wh to 960Wh batteries.

Step 5 — Frame Styles (Match to Your Riding)



Frame Type Riding Position Best For Pros Cons
Step-through Upright Commuting, casual, older riders, skirts Easy mount/dismount Less stiff
Step-over (diamond) Forward Sport, off-road, taller riders Stiffer, better handling Harder to mount
Folding Upright Commuters with limited storage, RV/travel Compact storage Heavier, smaller wheels
Cargo Upright Carrying kids, groceries, deliveries Hauls heavy loads Long, heavy

Recommendations:

  • Most commuters: Step-through (easier with work clothes)

  • Off-road or sport: Step-over

  • Apartment dwellers: Folding

  • Parents or hauling: Cargo

Step 6 — Tires (Thickness Matters)



Tire Type Width Best For Pros Cons
Standard 1.75-2.0" Pavement, smooth bike paths Fast, efficient Less comfortable on bumps
Hybrid 2.0-2.4" Mixed pavement and light gravel Versatile Compromise
Fat tire 3.0-4.0" Sand, snow, rough trails, comfort Very stable, comfortable Heavy, slower, less efficient

Recommendations:

  • Pavement only → Standard tires

  • Mixed use → Hybrid tires (sweet spot)

  • Beach, snow, or rough trails → Fat tires

What we sell: Standard, hybrid, and fat tire options.

Step 7 — Brakes (Safety First)



Brake Type Stopping Power Maintenance Best For
Disc (hydraulic) Excellent Low (sealed system) All e-bikes, wet conditions
Disc (mechanical) Good Medium Budget e-bikes
Rim (V-brake) Fair (poor when wet) High Avoid on e-bikes

Recommendation: Hydraulic disc brakes are worth the upgrade. E-bikes are heavier and faster than regular bikes — you need good brakes.

What we sell: All our e-bikes have hydraulic disc brakes.

Step 8 — Gears (More Isn't Always Better)



Gears Best For Why
Single speed Flat areas, casual Simple, less maintenance
7-8 speed Most commuters Enough range for hills
9-10 speed Sport, varied terrain More gear options
Hub gears (internal) Low maintenance, all weather Gears inside hub (protected)

E-bike specific: You don't need as many gears as a regular bike because the motor helps. 7-8 speeds is fine for most riders.

Step 9 — E-Bike Features Worth Paying For



Feature Worth It? Why
Integrated lights Yes Safer, never forget to charge
Rear rack Yes Carry bags, groceries
Fenders Yes No mud stripe up your back
Suspension fork Maybe More comfortable on rough roads, but heavier
Throttle Yes (Class 2) Helpful from stops, no pedaling
LCD display Yes See speed, battery, assist level
USB charging port Nice to have Charge phone on the go
Torque sensor (vs cadence sensor) Yes Feels more natural, smoother assist

Step 10 — E-Bike Weight and Portability



Bike Type Typical Weight Can Carry? Store?
Standard e-bike 45-60 lbs Heavy, need ramp for car Garage, bike room
Folding e-bike 35-50 lbs Heavy but compact Apartment, car trunk
Cargo e-bike 60-80+ lbs Very heavy Garage only

If you live in a walk-up apartment: Get a folding e-bike (under 50 lbs) or store outside (locked).

If you drive to rides: Get a folding e-bike or a hitch rack (not a trunk rack — too heavy).

Step 11 — Assembly and Maintenance

What to expect:

  • Most e-bikes ship 80-90% assembled

  • You need to attach handlebars, pedals, front wheel, and seat

  • Basic tools included (Allen wrenches, sometimes a wrench)

Ongoing maintenance:

  • Check tire pressure weekly

  • Clean and lube chain every 100-200 miles

  • Check brake pads every 300-500 miles

  • Battery: Store at 40-80% charge, not empty or 100% for long periods
