BAMF Full Nelson Betty Mountain Bike

The average height of a woman is about 4-inches to the south of a man. So it only makes sense to have a bike that is a little shorter on size but just as rough in attitude. BAMF stands for exactly what you think it does. The gang at BAMF thought they would make a bike for the ladies that wasn’t all pink or light blue. Like all the other killer bikes in the BAMF line, black is the color of choice.


Bikes are too personal to let some pretty Lexus induced paint job speak for who you are. If you ride a bike, really ride a bike, you know the cold burn on your face in the winter, the sound of hitting the ground and the tingle of a bloody knuckle. You don’t ride so you can put an ornament on your SUV or to get a frappuccino hoping to be seen…You hunt those types down on the trail and smirk as you rip past leaving them and their GPS wondering what happened?


All the BAMF bikes are black (like the guys at BAMF are going to fight over color pallets) and come with minimal decal and a killer 4-color (gold, white, purple and blue) sticker kit for you to create the look you want. Put the stickers on the bike, your car or your friend’s back. BAMF takes bikes seriously…like tattoos. They don’t want you to show up on the trail and see the exact same machine on the trail. BAMF wants you to make it your own. Bikes are a permanent fixture in their life and they pour that passion into their work. From the name alone, BAMF Full Nelson Betty, you get the idea they have strong hold on what makes a great bike.


The BAMF Full Nelson Betty is an aluminum 26” MTB ready to get it done on the trail. With a component package touting a RockShox Dart2, SRAM X.5 trigger shifters, X.7 front and rear derailleur and Tekto hydraulic disc brakes this bike is ready to go. The Full Nelson starts with a light and responsive BAMF Bad Ass 6061 aluminum racing frame. The RockShox suspension fork with 100mm of travel is a solid performer that keeps the front wheel tracking the ground over the roughest terrain. The SRAM X.5 trigger shifters are paired with the SRAM X.7 rear derailleur and SRAM X.7 front derailleur providing a precise shifting partnership. When the time comes to control the velocity of the Full Nelson the Tektro Auriga hydraulic brakes will be at your middle finger (BAMF humor). The BAMF MTB saddle adds a nice touch of comfort even for the hardest of riders out there can appreciate.  The alloy Truvativ Five-D crank with the 44/32/22 chainring combination will launch you ahead of your riding partners.


The BAMF Frame
The BAMF Full Nelson’s foundation is a lightweight BAMF Bad Ass 6061 aluminum creation with replaceable derailleur hanger, disc tabs and 1-1/8” integrated headset and water bottle mounts. The BAMF 26” MTB geometry is straight forward and solid. The 6061 aluminum is strong where it needs to be and light too while being dependable. The frame has a 27.2 seat post diameter and a 68mm English threaded bottom bracket. The head tube is designed to accept IS-2 standard threadless 1-1/8" bearings. BAMF stands behind the aluminum frame with a lifetime limited warranty against manufacturing defects. If you take a jump off a loading dock…sorry, that’s on you.


The BAMF Fit
Sizing a BAMF MTB is no different, or more difficult, than any other style of bike. By reviewing the size chart you will see a measurement called the “Eff Top Tube”, also known as the Effective Top Tube Measurement. This is what the top tube would measure if it was parallel to the ground. It is an imaginary line the runs from the center of the head tube to the center of the seat tube if the seat tube was extended like a traditional frame. The +/- 7° stem can also be flipped and adjusted for a lower back-friendly position to a more streamline position in minutes. The lower top tube keeps the center of gravity low and the makes for an easy approach to getting on the bike. This BAMF bike was designed with the user’s needs and comfort as the #1 priority.


The BAMF Feel
The BAMF crew spent a lot of time getting this MTB right. After racing 24-hour events, Single Speed World Championships, downhill, cross country just about any other trail induced event the BAMF guys get mountain biking. Scars (nature’s tattoos) have been our learning lessons and we know the importance of a great frame with good handling manners and mud clearance. The BAMF crew got together to bring back the grassroots appeal to mountain biking. To disappear down the trail and experience the terrain and forget about work is a feeling we all need on a regular basis. BAMF wants to make bikes simple to understand and easy to afford. Yes, they will probably make some expensive dream machines but they started at the soul of the MTB price points. The SRAM X.5 trigger shifters and SRAM X.7 rear derailleur will keep the 9-speed cassette actuated and the speed coming. Going through the woods is fun…flying though the woods with confidence is even better. The RockShox Dart 2 suspension fork will help guide you through the rough stuff and keep you tracking where you want to go. While hard-core riders try not to slow down the Tektro hydraulic brakes provide sure stopping power when it is needed.
