Overview
A 29 inch wheel mountain bike from Eurobike with 21-speed front and rear derailleurs, dual disc brakes and dual suspension, sold partially disassembled for home setup.
The model listing shortens the brand to EUROBKE but the seller is Eurobike, a budget mountain bike line sold mainly through Amazon. At 3.7 stars from 12 ratings, expect a basic entry-level build rather than a shop-quality bike, and plan on 10-20 minutes of assembly plus checking the included pedal thread instructions before riding.
- 29 inch spoke wheels
- Front and rear derailleur shifting
- Includes assembly instructions in the box
- Pedal threads differ left to right, noted in setup
Who it's for
Suits casual and family riders who want an affordable 29er for local trails and neighborhood rides. Less suited to anyone expecting a plush stock seat or shop-level fit and finish out of the box.
What buyers say
From Amazon customer reviews.
Reviewers who kept the bike liked the control and braking and reported getting compliments on its look during family rides, but more than one flagged the stock seat as uncomfortable.

Performance notes
