How this e-bike scores for different riding styles
Multiple riding modes, waterproof leather seat with foam, and versatile 7-speed drivetrain make it comfortable for casual rides. The 28 mph speed offers fun without being overwhelming for leisure riders.
The 40-mile range and 28 mph max speed make it capable for daily commutes, but the non-foldable design and basic 300Wh battery limit versatility. UL certification and integrated lights add safety for urban riding.
Front suspension, disc brakes, and 750W peak motor handle moderate trails, but the 1.95-inch standard tires and single suspension limit serious off-road capability compared to dedicated mountain e-bikes.
The 750W peak motor and 28 mph speed are respectable but fall short of high-performance standards. Limited by smaller 300Wh battery and average drivetrain components for enthusiast-level riding.
The 300-pound weight capacity is adequate for riders plus light cargo, but lacks rear rack, fenders, or cargo-specific features. The 300Wh battery may struggle with heavy loads over distance.
This bike scores very low as it's not foldable and has a large 62.48-inch frame length, making it impractical for apartment storage or public transit integration.
Our Verdict
The TST M612 electric bike is a budget-friendly option that packs surprising features into its $399.99 price tag. You get a 750W peak motor that can hit 28 mph and climb 30-degree hills, plus it's one of the few bikes under $500 with UL2849 safety certification. The bike comes with useful extras like LED lights, an LCD display, and a removable battery that takes 5-6 hours to charge. With 40 miles of range and four riding modes including pure electric, pedal assist, and regular pedaling, it gives you flexibility for different situations. The aluminum frame keeps weight reasonable while supporting riders up to 300 pounds, and the front suspension with disc brakes handles basic safety needs.
This bike works best for people who want an affordable way to commute short to medium distances or enjoy casual weekend rides. If you live in a city or suburb and need to travel 10-20 miles to work, this bike can handle it easily. It's also great for recreational riders who want to explore bike paths, neighborhood streets, or light trails without spending over a thousand dollars. The simple setup and multiple riding modes make it beginner-friendly, so even if you've never ridden an e-bike before, you can start easy and work your way up to faster speeds. The throttle option is perfect when you're tired or facing a steep hill.
However, this bike has some clear limitations you should know about. The 300Wh battery is smaller than average, which means it might struggle on long trips or when carrying heavy loads. The 6-month warranty is concerning since most quality e-bikes offer at least one year of coverage. If you need a folding bike for apartments or train commutes, this won't work since it's full-sized. Serious mountain bikers should look elsewhere too - the narrow tires and front-only suspension aren't built for rough terrain. The lack of reviews also means we don't know how it performs after months of daily use. If you can afford to spend $600-800, you'll get better battery capacity and longer warranty protection.
What We Like
- Amazing price at just $399.99 for a 750W motor and 28 mph speed - that's a steal compared to bikes costing twice as much
- UL2849 certified for safety, which is rare in this budget range and means it passed strict electrical and fire safety tests
- Comes with both throttle and pedal assist plus 4 different riding modes so you can ride it however you want
- Gets 40 miles on a single charge in electric mode, enough for most daily rides without worrying about running out of power
- Already 90% assembled when it arrives, so you can get riding quickly without spending hours putting it together
What Could Be Better
- The 300Wh battery is pretty small compared to most e-bikes, which means less power for hills and shorter range with heavy riders
- Only 6-month warranty coverage is really short - most e-bikes give you at least a year or two of protection
- Just 3 customer reviews means it's a newer or less popular model, so it's harder to know if it holds up over time
- No rear rack or fenders included, so you'll need to buy extras if you want to carry stuff or ride in wet weather
- The 1.95-inch tires are pretty narrow for a mountain bike, so it won't handle rough trails or soft terrain as well as fat tire bikes
