Let customers speak for us
from 26 reviewsBought the 8-person model — heavy duty and exactly what we needed for our family.

The 4x8 shelter is spacious and feels very safe. Glad we made the investment.

Our 6x8 shelter is huge. More than enough space for our extended family.

We went with the 5-person shelter. The steel feels rock solid and gives real peace of mind.

Quiet and powerful, performs well in saltwater.

I bought the blue version for my son — fast shipping and solid build. He rides it every weekend.

The build quality is top-notch.

Customer service helped me decide between the green and red. Ended up with green and love it.

Works fine, but the setup guide could be more detailed.

Took it out this weekend, no issues at all.

Ordered the MotoTec Pro 60v Blue. Arrived on time and packaged well.

Smooth performance and quick delivery.

I chose the blue bike. Works great, though the shipping box had a small dent — no damage to the bike.
