GT Slammer 20 bicycle, blue
GT Slammer 20 bike
GT Slammer 2021 is a universal freestyle BMX bike suitable for beginners or moderately advanced riders, from a height of approx. 150 cm. It has a quality frame designed by professional GT riders with Hi-ten steel tubes and a fork. Thanks to the universal geometry, it is suitable for all BMX disciplines - Street, Park, Dirt. The bike is equipped with high-quality components for this category - such as three-part Cr-Mo cranks with an octagonal axis, suitable for BMX classic 25/9 teeth. The popular TWISTER is also part of the equipment.
Steel frame
The most affordable, durable material that absorbs vibrations well, but it is necessary to expect a heavier weight.
20” wheels
Wheel size used mainly on children's bikes and balance bikes. The size usually correspond to the frame size of the particular bike.
Cantilever brakes
Classic rim brakes are the most affordable, but less used today. They are more difficult to set up.
Rigid fork
You will appreciate the lighter weight and stiffness, especially when riding on the road or bike path. Minimal service.

All bicycles at the MTBIKER shop are new, not-ridden, from an official distributor and with a full warranty. Several brands even offer a lifetime warranty on the frame after registration. We perform all warranty services in MTBIKER stores after personal delivery or after sending the bike (or its part) by courier.
- The bicycle is taken out of the manufacturer's box
- The bicycle is assembled, inspected and adjusted (front and rear derailleur, shock, fork, wheels,...)
- The bicycle is carefully packaged back into a box and shipped
- If you order a bike for in-person pick-up or home delivery, the bike will be waiting for you assembled and checked
- If you order a bicycle via courier to your home address, the following must be done at home:
- Take the bike out of the box and carefully remove safety material and foils
- Mount handlebar to stem (1 minute, 4 or 5 mm hex hey is needed).
- Mount front wheel to fork (1 minute, without the need of any tools if the bike has a quick release).
- Loosen the screws in the headset, straighten the stem with the front wheel, tighten the upper screw on the fork and then tighten the headset (2 minutes, 4 or 5 mm hex key is needed).
- Mount the pedals to the cranks while lubricating the thread and carefully mounting it the right way (1 minute, 8 mm hex key or 15 mm wrench).
- Mount seat post to frame (10 seconds, without needing any tools if the frame has a quick link).
- Inflate the tires or fork and shock to desired pressure (2 minutes, pump needed).
- Check the tightening of hex keys and quick-releases (2 minutes, 4 and 5 mm hex key is needed).
- Go for a test drive! Handle your bicycle carefully until you get used to it. If the bike has disc brakes, their performance will be limited from now on - they will gain their full power after 4-5 strong brakes at higher speed.
