Today I had a great conversation about the Tern GSD models, the Tern GSD S10 and the Tern GSD S00. We discussed the pros and cons, which seemed like a good thing to share with you! If you aren't familiar with the Tern GSD electric cargo bike I would recommend starting with my review of it here.

* Please note that there used to be a difference between the kickstands on the S00 and S10 but they are now the same.
Talking Through the Differences
The key differences to me are the motor and the drivetrain. The motor is something you can't change after the fact. As a Bosch dealer, I can never upgrade a motor, period. The internally geared Enviolo drivetrain would be very expensive to upgrade after the fact. The drivetrain we could put a price tag on, but the motor upgrade we can't. The Performance CX has more torque and more max assistance over the Performance motor. If you need that, you can't get it later on.
If you break down the price by accessories & battery differences it doesn't make sense. The Tern GSD S10 ($4000) + Cargo Hold Panniers ($150) + Abus 5750L frame lock ($90) + battery price difference of a 400wh and 500wh ($191) *please note you can't swap batteries but I'm talking hypothetically. This all adds up to $4,431. As I mentioned, you can't put a price on the drivetrain or Enviolo drivetrain.
If you are trying to do this on a budget and every dollar counts, go with the S10.
In general, you can't go wrong with the Tern GSD S10 or S00 electric cargo bike.
If you want more power with the Performance CX motor or you want an internally geared hub (I ride this Enviolo daily and LOVE IT) or maybe you want the mango yellow, then the price is very worthwhile for the S00.
