Who it's for

What buyers say
From Amazon customer reviews.
Reviews split widely. Positive reviewers praise the power, suspension, and value for money, with one large rider reporting strong performance and comfort over rough terrain. Negative reviewers report real problems: one bike arrived damaged with missing parts and non-working brakes plus slow customer service response, another arrived with cosmetic damage and a dead battery, and a third found the listing's model naming confusing versus the bike actually shipped.
Strengths and trade-offs
Drawn from this product's published specifications.
- Strong torque and hill-climbing power reported by riders
- Front suspension smooths out bumps well
- Bluetooth connectivity and cruise control on some units
- Multiple reports of shipping damage or missing parts
- One reviewer described customer service as slow to resolve issues
- Listing name (Thunder vs Thunder Pro ST) confused at least one buyer
Performance notes
Riders who got a clean unit report strong torque for hill climbing and comfortable suspension over bumps, with one large rider reaching close to 38 mph on flat ground. Multiple reviewers, though, described receiving a bike with cosmetic damage, an over-tightened rack screw, or a dead battery needing a full charge before first use.
