Whether you're looking for a bit more comfort on leisure rides, exploring offroad paths on weekends or shredding the trails at Cathkin Braes then a Mountain Bike is ideal.
If you're just starting out or want something more efficient for longer rides then go for a Hardtail which only has a suspension fork making the bike lighter and pedal faster on hills and flats.
If you're planning on pushing your limits on technical trails and love shredding the downhills then go for a Full Suspension which has both a suspension fork as well as a rear suspension shock to offer maximum performance and stability on big features like jumps and drops.
