I just got the TST R002 today via FedEx! I had it out of the box and put it together in under an hour.

TST is a pretty good budget ebike brand. I've been happily riding the TST Carrier for the past few months for taking my kids to school and back:

The R002 is a small full suspension moped-style ebike with a 1500w motor.

Compared to my vintage mopeds, the TST R002 is quicker off the line and completely silent with none of the 2-stroke engine noise. At 72 pounds, the R002 is about 40 pounds lighter and much more nimble than my 1978 Motobecane Mobylette 49cc moped.

The TST R002 is a fun little bike with full suspension and fat tires. It has a ton of torque. It does need to be paired via Bluetooth and unlocked in the mobile app to access class 3 speeds (28 mph instead of 20 mph), but once that is done it feels like a proper little electric moped.

Two things I would change:

I prefer a twist throttle. This one has a left-hand thumb throttle. If you are pedaling in PAS 4 or 5, the throttle is not really necessary so it is not a huge deal, but I still prefer a twist throttle.

The R002 has mechanical cable brakes. The TST Carrier has hydraulic brakes, which are definitely better.

Can't wait to put a few more miles on it! I'll try to follow up with more...
