Bottom line

The KBO Oasis is an entry-level cruiser electric bike with 3" tires and a 500W motor. The above-average 720Wh battery returns an impressive range above KBO's rating of 55 miles. Experts praise the blend of comfort, style, and affordability. However, it's heavy, provides underwhelming power output in PAS levels 1 and 2, and has inconsistent motor engagement. Additionally, the step-over frame's height range seems exaggerated. Despite these drawbacks, the Oasis remains a "solid" choice for recreational rides and commuting, with included accessories such as lights, fenders, and a rear rack.
