The ride feel of the ST1-T is def more smoother than the Smart motion pacer!
Even in terms of componentry, ST1-T is slightly ahead of the pacer. Here is what I see...
Shimano XT derailleur + Schlumpff drive
Vs Deore derailleur and no front chainrings.
Supernova lighting on the ST1-T
Vs some fancy LED lighting and average front light on the pacer.
Ergon grips on the ST1-T
Vs some cheap non-lock on grips on the Pacer.
Big Ben tires w/ Green guard protection
Vs cheap kendra tires without much protection on the pacer.
Carbon fork on the ST1-T vs the aluminum fork on the pacer (carbon fork is lighter and absorbs more vibration than the Al)
Well known and reputed TMM4 Sensor on the ST1-T
Vs unknown bottom bracket torque sensor on the pacer.
Oh!With the new 630Whr battery, you're looking at 50+ miles on the ST1-T. But here is a slight advantage to the pacer. You can go upto 800whr with an upgrade.
Both bikes can be had a with suspension seatpost.
I know Chris at
Lectric and think he is a great guy but having ridden those two bikes, ST1-T comes slightly ahead in terms of build quality, support compared to the pacer [especially true if both are within few hundred $ of each other]. At full MSRP, you may want to think more.
Now, if there is a dealer willing to stand behind either of those products, then it's a different story. But just going by ride quality and bike componentry, ST1-T is def better.
