Cannondale 27.5 Inch Wheel Cycling

Where do you plan to ride?

Choose a gravel bike if you plan to ride a mix of terrain—dirt, pavement and other loose surfaces.

Bike power

Electric gravel bikes lets you ride farther, faster. Check e-bikes rules where you plan to ride.

Handlebar shape

Drop (curled) handlebars are most common; some models offer flat bars.

Frame material

• Aluminum: Smooth ride, more affordable
• Carbon: More vibration-absorbing ride; lightweight but higher cost

Tires

• Tires are treaded or knobby for durability and traction
• Wider tires are better for rougher terrain; narrower tires are ideal for smoother surfaces

Get the right fit

• Start with the brand's size chart
• For the best fit, try the bike in person

Types of bike helmets

• Mountain bike: Rear-head coverage for off-road trails; often includes added ventilation
• Road bike: Lightweight, aerodynamic; designed for maximum airflow
• Recreational cycling: Budget-friendly choice for casual riding

Fit tips 

• Measure the largest part of your head with a flexible measuring tape (or use string, then measure it)
• Check the brand's sizing chart
• Aim for a snug fit 
• Between sizes? Choose the smaller size 

Added protection 

Look for technologies that reduce rotational forces during a crash, like Mips, WaveCel or KinetiCore.

Features 

• Vents: More vents improve airflow and reduce weight
• Visor/brim: Keeps the sun out of your eyes
• Chin bars: Extra protection for downhill mountain biking

Which class of e-bike do you want?

• Class 1 e-bikes provide motor assist only when you pedal, up to 20 mph.

• Class 2 e-bikes have pedal-assist up to 20 mph; they also offer throttle power that doesn't require pedaling.
• Class 3 provides assist when you pedal, up to 28 mph.

What type of bike do you want?
Electric bikes come in many formats including mountain, urban, cruiser, cargo and folding bikes.

Consider motor power
Motor power is measured in watts (W) and range from 250W to 750W. E-bikes with higher watts offers better acceleration, climbing and hauling performance.

Consider battery capacity
A higher watt hours (Wh) number indicates greater battery capacity, which gives you more riding time between charges.
