Overview
A 20 inch fat tire electric bike built around a motor rated to 1500W peak, with a 48V 15Ah removable battery and front and rear suspension. Aimed at riders who want one bike to cover commuting and rougher terrain.
TST lists a 750W motor with a 1500W peak rating, worth knowing before you buy since the peak figure is a burst number, not sustained output. Front and rear suspension plus 20x4 inch tires target rough terrain and long commutes rather than pure speed. At nearly 88 lbs before gear, this is a bike you ride, not one you carry up stairs daily.
- 48V 15Ah removable battery, 6-7 hour charge time
- Front and rear suspension with 20x4 inch fat tires
- 7-speed gearing with 3 selectable ride modes
- 450 lb max load, ships about 90% pre-assembled
Who it's for
Riders who want one bike to cover daily commuting and occasional trail or beach riding, with battery range for multi day use before a recharge. Less suited to anyone who needs to lift or store the bike indoors regularly given the near 88 lb weight.
What buyers say
From Amazon customer reviews.
Buyers who left reviews were mostly positive: several called assembly quick and straightforward, praised the smooth ride and suspension, and said customer service responded well to issues. The complaints worth knowing are one buyer reporting the brakes failing twice within days of setup, and another noting the companion app doesn't work on Android despite being advertised.
