Giant electrifies Trance and Stance for 2019

New e-MTBs offer cleaner integration, updated batteries and motors

Giant's new e-MTB range boasts the new Yamaha SyncDrive motor for up to 360 percent assistance when pedalling, a quick response time and a battery that recharges to 60 percent in one hour.

The popular Stance, Trance and Trance SX get the e-bike treatment, giving a range of e-mountain bikes that cover everything from a 120mm intro bike for exploring, to a beefier 140mm trail machine.

Giant has worked with Yamaha over the years on its SyncDrive motor and this has seen updates for 2019 with two models: the Pro and the Sport.

The updated motor gets two battery options, with 500Wh or 400Wh capacities. These new motors have found their way in to three mountain bike model families, with 150mm, 140mm and 120mm of rear wheel travel, covering a range of price points.

SyncDrive Pro and SyncDrive Sport motors

The Pro gives up to 360 percent assistance (within the 250W limit), and up to 80Nm of torque — these torque figures are about as high as any e-bike motor gets.

This power is provided to the cranks fully up to 120rpm in the three higher power modes, while it's provided up to 110rpm in the two lower modes.

The Pro motor also reportedly benefits from a very quick response time, 190 milliseconds, to crank inputs. So, in theory the motor shouldn't have much discernable lag when riding up technical climbs.

The clutch mechanism inside and the internal ratchet have been improved as well, to help with the reactivity of the motor, while the 168mm Q-factor (distance between the cranks) is pretty low. Giant claims the motor weighs 3.1kg

The Sport motor is built for cheaper bikes. As such, it weighs a touch more at 3.48kg and has a slightly slower reaction time to crank inputs thanks to a longer clutch engagement time.

It still provides up to 250W of assistance, with up to 80Nm of torque, though that's only available up to a pedalling cadence of 110rpm. The crank/bottom bracket interface is square taper.

The motors react thanks to 'PedalPlus' technology, which uses torque sensors (for pedal inputs), speed sensors (not linked to the crank's rotations), as well as motor and pedal rotation sensors to make sure the motor reacts properly to the rider's inputs for a natural, efficient and immediate assistance — according to Giant.

The accompanying battery is better integrated into Giant's frames, mounting lower down in the down tube for better weight distribution.

There is a two-lock system, which Giant says makes life easier, while there's also smart charging, allowing recharging up to 60 percent of full capacity in one hour. Increased space between battery cells means the battery should heat up less too.

With the 500Wh battery, Giant is claiming up to 150km of range in Eco mode with the less-powerful Sport motor and 110km with the Pro motor. In the top 'Power' mode this drops to 50km and 45km respectively. The 400Wh battery option obviously provides correspondingly lower ranges.

The Trance SX E+ Pro is a 140mm trail and enduro bike, coming equipped with 160mm of front suspension. Giant says that this is for advanced and aggressive riders looking to ride more technical terrain with greater ease.

The rear suspension utilises Giant's long-used Maestro linkage to deliver the 140mm of travel to the aluminium frame. The bikes come with 27.5in wheels and are specced with 2.6in rubber.

A size Large bike will have a reach of 452mm, 469.5mm chainstays, a 66-degree head angle, 73.5-degree seat angle and 1,233mm wheelbase.

Both models of the Trance SX E+ Pro (the '1' at €5,999 and the '2' at €4,599) will get the SyncDrive Pro motor and 500wh EnergyPak.

Giant Stance E+

The Stance E+ is aimed at slightly more recreationally focussed mountain bikers; those looking to get in to e-MTBs as a starting point or those whose position on the bike favours a less aggressive style of machine.

Giant uses a linkage-driven single pivot suspension for the Stance E+, rather than the Maestro suspension found elsewhere. These aluminium bikes will have 120mm of frame travel and 130mm of fork travel.

All four Stance E+ models will use the SyncDrive Sport motor, and the top three models (the '0', '1', and '2 Power') get the 500Wh EnergyPak. The entry level '2' model gets a 400Wh version of the battery.
