What is the HD/e?  (back to top)

The Jones LWB HD/e is based on the Jones LWB, a design that has proven itself as one of the most versatile bikes around, and it's little wonder: Jones Geometry and the long wheelbase puts you in a position that's comfortable and relaxed, yet very efficient and great for everything from technical trails to long road rides!

HD/e stands for heavy duty and electric. The frame is built stiffer, stronger, and longer. This frameset is an excellent starting point for building up a fully loaded touring bike or for a DIY e-bike project. If you’re in need of a heavy duty frame for touring, bikepacking, mountain biking, commuting, gravel, or road riding, the Jones LWB HD/e has you covered!

The Jones LWB HD/e frame is TIG welded from seamless 4130 chromoly tubing with butted tubing. After welding, the complete frame is heat treated. Our LWB HD/e steel frames have a great feel to them that is stiffer, stronger and with a little more weight than the non HD/e version (~ 300 grams). Perfect for heavy loads or for an electric bike.

The Jones LWB HD/e has a standard 68 mm English / BSA threaded bottom bracket which is one of the most commonly used bottom bracket sizes. This allows the frame to be built up with either a regular bicycle crankset, or a mid-drive e-bike motor.

We offer this frameset, built up into complete bicycles and e-bikes. This frameset does not have any extra brackets or mounts that make it an e-bike frame. It does, however, have enough clearance for a motor as well as being made stiff and strong enough to handle a heavier rider, motor, and/or lots of cargo.

Here is a video where Jeff talks about this new bike.
