Perhaps one of the technical members can verify something about the Giant’s 2020 SyncDrive Sport motors. My research of the newest Syncdrive reveals differences between 2019 vs 2020 that may be more significant than I first realized..The big ticket item was updating the motor from four motion sensors to six. Giant calls this PedalPlus technology and the result is having an improved automatic Smart Assist mode. (Was this not available before??)
“The motor now also features six sensors (four before), enabling the Smart Assist technology that calculates the amount of torque, pedaling cadence, slope and speed while riding. Based on those calculations, it determines the amount of power needed to provide a smooth, natural riding experience. The motor engages instantly when power is applied to the pedals.
Next to the five levels of support modes, this new selectable Smart Assist mode automatically regulates the power according to the need and helps to improve battery range. Basically, the idea is to give you the option to run that mode all day long, without having to give mode-selection a second thought. To activate the Smart Assist mode, you have to cycle into the opposite direction of the regular modes via the thumb buttons on the RideControl unit, past the off mode.
A higher cadence support now reaches all the way up to 170 rpm, meaning that it tapers off much later than the old version, which lost power around 80 to 90 rpm. With full power up to 130 rpm, the mechanical range is now much bigger for full support. Also, the motor noise could be reduced considerably. Official numbers are communicated at a reduction of roughly 15%, although it’s hard to put into percentage numbers and it can easily be argued that it comes down to much more than that.”
Additionally the ability to increase assist levels to 350% (nice) looks to be a bonus on top of the increased cadence support. (Not really applicable to me..)
Oddly to looks like Yamaha’s in house PowerDrive series remains at four sensors for 2020.
