8 reasons not to buy

A reviewer finds the suspension fork’s preload knob doesn’t change much, and multiple testers bottom out the fork.
Experts caution that starting in max assist can cause the front wheel to lift.
A reviewer says riders below 5'11" may find the TST Defender too large.
Three testers receive bikes with faulty controllers that result in inconsistent power output and speed across the five PAS levels.
One test bike is defective, and TST customer support doesn't respond initially, then avoids helping.
Neither the TST Dreamer nor Defender comes with a taillight.
TST lists many contradictory product specifications on its website.
The IPX4 water resistance rating means the e-bike shouldn't be used in heavy rain.

Bottom line

The Defender and Dreamer are step-over and step-through versions of TST's fat-tire commuter e-bike. This budget machine is advertised as versatile and powerful, and reviewers indeed praise its strong torque and ability to handle light off-road terrain. However, the bike certainly cannot "tackle any trail," as TST claims. Both recommended height ranges also seem exaggerated, and multiple testers report issues with the controller tuning, and one is disappointed by TST's customer support. For budget-restricted buyers, reviewers think the Defender and Dreamer are good options, but reports of poor customer support add risk.
