Andrew Walker

When not at work rest assured, he’s either spending time with his wonderful wife Jennifer, logging miles on one of his favorite gravel back roads on a bike ride with friends, or cruising one of the area’s many amazing mountain bike trail systems.

Jesse Cecil


Jesse has a deep conservation ethic, and views development of outdoor recreation as the path to a brighter future for WV communities.

A child of Appalachia, Jesse was born in Roane County, West Virginia, and grew up in the Blue Ridge Mountains of Floyd, Virginia. He moved to Morgantown nigh 20 years ago to attend undergrad at WVU and never left. Though riding bikes since he was knee-high to a grasshopper, Jesse is a relative noob to the modern mountain bike scene — he hit the trails in 2017 and never looked back. He and his wife Kristi have two daughters, Seneca and Isla Jane, who are naturally being raised to love the outdoors and ride bikes with gusto.

Bonnie Ammons

Member at Large

Originally from Frederick, Maryland, Bonnie moved to Morgantown in 2000 after graduating from James Madison University. Bonnie grew up running around in the woods and spent summers in her younger days sharing that love by working in outdoor tourism as a raft guide and commercial cave tour guide. Early in her time in WV, she took up road biking and triathlon with her husband, Jeff, before having 2 energetic boys and later embracing the switch to Mountain Biking as a family sport. Bonnie quickly fell in love with riding in the woods and currently is an enthusiastic Coach-Volunteer with our local NICA (National Interscholastic Cycling Association) team. Go Trailhawks! She enjoys traveling to other mountain biking destinations with her family and looks forward to encouraging others to enjoy the beauty and challenge that Morgantown Area trail systems have to offer. Bonnie is especially passionate about encouraging women to ride and for whole families to ride together because riding bikes is FUN!

John N. Herod, III

Member at large

John Herod is a native West Virginian and life-long ambassador of and advocate for mountain biking in West Virginia. A successful semi-pro downhill racer from 1998 to 2004, he won the NORBA Mid-Atlantic Cup in 2002. In 2014 he co-founded the WV Enduro Series to showcase the state’s unique, rugged, and beautiful trail systems. During his tenure as the series organizer, 2014 to 2019, he cultivated successful partnerships with non-profit groups, public and private land owners, and local business to raise the profile of riding in the mountain state more than doubling rider participation after the first year of the series and attracting riders from over a dozen states. 
Herod sees a bright future for cycling in West Virginia and believes that cultivation of a robust trail system and preservation of the state’s natural resources provide unique economic development opportunities in ecotourism for the area. He looks forward to the challenge of his term as president of the newly-formed MAMBA organization. 
When not riding and trail building, Herod works as the owner and operator of Better Builders, LLC. He is a third-generation, master tile setter, general contractor, and amateur photographer. He lives in the City of Morgantown with his wife, Rebecca, and faithful doberman trail companion, Lucky.

BJ Knabenshue

Member at Large

BJ Knabenshue is a systems engineer developing spacecraft simulators supporting NASA, and a lifelong resident of WV. He started riding in the woods outside Buckhannon, WV early in his teens in the days of bar ends and cantilever brakes. BJ is a graduate of West Virginia University , and wrenched at various bicycle shops during college to feed his bike habit.

Over the years, BJ has ridden both road and cyclocross, but his heart is in mountain biking. He loves to jump his bike off of things and sometimes even land it. Cycling is common thread across BJ’s life, he met his wife Traci on a bike and they now enjoy passing their love of cycling on to their children, who are learning to mountain bike on the Morgantown trails. He joined the MAMBA board of directors in March 2021 to help protect and grow mountain bike opportunities in the Morgantown area.

Drew Gatlin

Ex Officio – Municipal Liaison

Drew can’t figure out if he likes tinkering on or riding bikes more. He works as an engineer and has a bad habit of serving on too many boards and commissions, due to his dedication to public service and healthy community development. Although he grew up riding on the road in flat country far away, his relocation to West Virginia kindled a fascination with mountain biking, trail construction, and land management. Drew was a founding member of MAMBA, and served on the board of the directors as the organization’s secretary from December 2019 through February 2021, resigning to address the need to maintain a healthy work/life balance. Drew continues to interface with MAMBA in an ad-hoc technical and advisory capacity.
