An electrically assisted road bike, the Giant Road-E+ is designed to get you up to speed quickly. With a motor situated in the middle of the bike and a battery that sits along the downtube, it propels you up to speed faster than a regular bike, without hampering handling performance. The Road-E+ range consists of two models, the Road-E+ 1 and Road-E+ 2.
Disc brakes and a full road 2x11 speed drivetrain adorn both models, as well as larger tyres to deal with the greater speeds and heavier weight from the motor and battery. The road geometry, drop handlebars and 700c wheels make sure you’re well positioned to cruise up the climbs.
A road bike like no other, the Giant Road-E+ has an ALUXX SL aluminium frameset that is strong and lightweight. The Giant motor sits central and low where the bottom bracket is, maintaining an optimum weight distribution. The battery is integrated into the downtube, keeping the lines smooth and stylish.
Internal cable routing keeps everything nice and neat and a rubber frame protector under the downtube prevents harm coming to the battery or motor. A tapered headtube couples with the tapered steerer on the fork, utilising Giant’s Overdrive system for greater stiffness. The ALUXX SL aluminium of the fork matches the frame, for stiff and direct steering. A 15mm quick release axle further increases stiffness, while not compromising convenience.
Giant is a fully-fledged racer with the addition of a 250W Yamaha SyncDrive motor and a 500Wh battery pack. - Road.cc
With a fully integrated electric assistance system, the Road-E+ keeps the addition of a motor subtle. Both the Road-E+ 1 and Road-E+ 2 come with a Giant SyncDrive Sport, featuring a Yamaha motor putting out a maximum 80Nm of torque from the 250W power. The Giant RideControl manages how much power is given to assist pedalling input. Three modes are available: Eco, Normal and Power. A screen attached to the handlebars shows all the information you need to know, including battery power, mode and speed.
The battery on the Road-E+2 is the Giant EnergyPak 400Wh and on the Road-E+1 is the bigger capacity 500Wh. Both are recharged with a fast charger to speed up times when the juice is low. Giant claims the range of the bike to be Eco: 65<130km, Normal: 45<80km, Sport: 25<60km, but will vary depending on conditions.

Shimano road gearing gives a wide range to tackle any ascent comfortably and disc brakes control speed on the way down.
Both Road-E+ models get Shimano road gearing, with the Road-E+ 2 sporting a 2x11 Tiagra drivetrain. It has a wide 11-32T cassette so there’s no lack of gearing options. The Road-E+ 1 gets a combination of 105 and Ultegra components for a higher end shifting experience.
Braking duties are not short-changed, with disc brakes on both models. The Road-E+ 1 gets TRP Spyre mechanical disc brakes with 160mm rotors for efficient stopping power. The higher level Road-E+1 gets Shimano’s R785 hydraulic calipers with R685 shifters and levers. These give massive stopping power in all conditions, boosting confidence on descents.
Giant’s in-house wheels adorn both models, keeping it in the family while still offering a stiff and lightweight ride. The 700c road wheels are fast rollers, offering little resistance to get you moving in no time. The entry level model gets the SR-2 wheels, which are disc specific and responsive to the extra electric assistance. It is also kitted with Giant PR-3 tyres in a 32c width. The wider than usual tyres offer fast rolling and extra comfort for the weight addition of the electric motor and battery.
The higher end model gets Giant’s PR-2 wheels. They are lighter weight, yet just as strong. They are also disc specific and also feature 15mm axle compatibility in front. Schwalbe Durano Performance Line tyres are wrapped around these wheels, also in 32c width for the best performance.
Giant’s wheels are lightweight and stiff and matched to the 32c tyres for great control.
The Giant Road-E+ range is an electric road bike that brings the performance to you. With a fully integrated motor and battery, it’s hard to tell it’s electric until you start pedalling. The motor assists your pedalling up to a limited 15mph, helping you climb even the steepest climbs.
It’s great for shooting away at traffic lights, making it a great commuter. The range can vary from 25-130km, dependant on the power usage, meaning that even longer commutes are in reach. Road style drivetrains from Shimano give high end performance shifting and braking, keeping you well in line with you un-motored friends.
