KHS BNT 29er Mountain Bike

XXL Bikes from Big & Tall Bikes

If you're looking to order a bike that is truly designed for the big and tall, the KHS mountain bike is your solution. Our 29er XL mountain bike was designed by Lennard Zinn in order to ensure that even the tallest and widest had an affordable ride that fits just right. From the cranks to the handlebars, you can expect more comfort and a smooth ride from this sturdy, durable bike.

This bike is the mountain bike evolution based on the success of the KHS Flite 747 road bike and the next step on Lennard's journey to create the perfect bike for every type of rider.

The Best Mountain Bike

You want a versatile and efficient bike to get you moving from the bottom of a mountain to the top! Let the KHS mountain bike take you for a ride. Available as an XXL bike up to XXXL, we promise that you will be able to handle any mountain trail as well as bike paths, dirt roads, and streets.

Latest Features

The XXL and XXXL sizes come with Shimano SLX Derailleurs and Shimano 1x12-Speed Shifters, Stan's NoTubes tubeless wheels, 200mm cranks, and a Marzocchi Bomber Z2 Fork with 120mm of travel.

Please note that the pedals are not included with your purchase and must be bought separately.

How to Order

The bike comes to us from KHS partially assembled. You have two options for assembly and shipping:

  1. We at Zinn Cycles complete the bike assembly and ship it to you fully assembled. Please allow 2-4 weeks for assembly, (plus additional time for shipping).
  2. We ship the bike boxed as-is from KHS (partially assembled). You will need to take it to a bike shop to have this done unless you are an experienced bike mechanic. Below is a checklist of items that require a mechanic’s expertise to assemble the bike when you get it.


**When checking out online, choose one of the two shipping options: complete bike fully assembled or partially assembled.



KHS Bikes are partially assembled at their factory in Taiwan. Zinn Cycles cannot be responsible for the partial assembly performed by KHS. Issues with factory assembly must be handled directly with KHS


KHS Bike assembly checklist - needed if you choose the partially assembled option.

  • Install stem and handlebars.
  • Install grips.
  • Install brake levers and shifters (cables come separately from one another).
  • Install rear derailleur.
  • Install both wheels.
  • Check bottom bracket cups on both sides for correct torque of 40 Newton-meters (Nm).
  • **Remove the large black crank-arm fixing bolt and apply a healthy amount of blue medium strength loctite to the bolt.
  • **Check pinch-bolt threads on the left crank arm and torque to 10-Nm.
  • **Then torque the large crank arm fixing bolt with 8mm allen wrench to 30nm.
  • Check and true wheels.
  • Check tire pressure.
  • Install brake rotor to wheel and ensure proper bolt torque.
  • Verify brakes are aligned and not rubbing.
  • Bed in brake pads.
