Considering the Giant Road E 1 Pro has a max speed of 28mph and puncture-resistant tires, they come dangerously close to being the best electric road bikes. But there’s more to it than that. It’s lightweight, weighing only 40 lbs, and the ability to travel up to 100 miles on a single charge.

Why We Like It – Giant Road E 1 Pro

A champion on the hill, thanks to 80Nm torque and pedal assistance, the Giant Road E 1 Pro is perfect in the hands of commuters, professional bikers, and newcomers who want just a bit of help.

Pros
  • Powerful performance; 28mph max speed
  • Puncture-resistant tires
  • Lightweight, only 40 lbs.
Cons
  • Electric assistance mode feels janky

Durability & Build Quality

The ALUXX Giant Contact SL aluminum frame is lightweight at 40 lbs. A few pounds heavier than some, but still lighter than most. The D-Fuse seatpost has some good give to it for added comfortability and flexibility. The handlebars are Giant Connect 31.8mm, curving back for your typical mountain bike design. However, the pedals are durable but could use some extra grip.

Performance (Speed & Acceleration)

The Yamaha motor Giant SyncDrive Pro is packing some serious torque, up to 80Nm, with a top speed of 28mph. That gives it exceptional road riding power on hills. The Giant performance riding experience is heightened with the crankset Giant custom 34/50T, allowing for 170 rpm cadence. However the Giant RideControl Evo assistance could use some tweaking. The Giant Road E Pro Mountain Bike might feel janky when assistance cuts off, making you feel like you need to pick up the slack immediately.

Range & Battery

On a good day, 75 miles is what the Giant Road E 1 Pro Electric Bikes 36V 13.8Ah lithium battery pack can handle. However, eco mode will help the e bikes ride longer, up to 100 miles. Packaged inside is a smart charger Giant EnergyPak 6A combo.

Safety Features

Giant tubeless tires have much lower rolling resistance, and are puncture-resistant; tubeless ready tires are smoother overall. Derailleur Shimano Ultegra hydraulic disc brakes are far superior than previous models, offering better control over various weather, ergonomic, with increased stopping power for a safer e bike riding experience. The Trek Domane+ has the option to add headlights.

Value

With a bit of extra tweaking to the assistance mode, the Giant Road E 1 Pro makes its way to the top of our selected road bikes. It has the power, especially on hills; it has the puncture-resistant tires; it’s even lightweight. More importantly: it’s priced fairly, though a bit on the expensive side. Your budget option is the Orbea Gain eBike. For more performance, the Specialized Turbo Creo SL is packing a bit more punch.

Giant Road E 1 Pro Wrap Up

The Giant Road E 1 Pro has geometry that makes sense, the kind of design that distributes your weight evenly. Along with the integrated power Road E+ Pro can commute like a champ. After all, a max speed of 28mph and picture-resistant tires are integral if you plan on riding on the road. Just be sure to disable electric assistance when you aren’t on an incline.
