Do you provide bikes and other equipment?

For liability reasons, bike rentals and other equipment are not provided. However, XEN MTB will be happy to pick up your bike and bring it to the ride for you. Check the map of Southern California bike shops that rent mountain bikes near you.

If I contact you today, can we ride tomorrow?

Most tours are done on weekends. If you require a mid-week tour, sometimes XEN MTB can accommodate that request. It would be best to contact XEN MTB at least one week before your desired trip to work out the details. Be sure to check availability before booking a tour.

What if I have more than four people that want to ride?

For the past 10 years, your ride leader has had experience with group sizes ranging from a few people to nearly 50 at a time. Smaller group rides with people you know personally are the best rides. So that’s why there’s a four-person guest limit.

Are there more areas to ride around Southern California?

Yes, there are dozens of public parks and your guide has experience with just about all of them. But the rides featured on this website are the best among them.

Will you do a tour for just one person?

Yes! But the more people you bring (up to four max), the cheaper it’s going to be per person.


Do you provide transportation to the rides?

For liability reasons, NO, XEN MTB does not provide transportation of passengers as a service.

On the Ride

Can you fix my bike if it breaks down?

You are expected to be able to work on your own bike and have all the tools and supplies you need with you on the ride. That said, in an emergency, your guide can assist with most necessary trail repairs like flat tires, broken chains and even some catastrophic failures. But that shouldn’t be an issue if you had your bike checked out before riding!

I’m slow. Is that OK?

Yes, that’s perfectly fine! Your guide is slow too. But just be sure your buddies are OK with that! And remember, there’s no shame in walking. But that said, you shouldn’t try a ride that you know you’re not physically or technically able to do. When you contact XEN MTB, your guide will discuss your experience and recommend rides suitable to your abilities.

Am I going to be left behind?

We ride as a group and stick together for safety and camaraderie. It’s just more fun that way! In the 10 years that your ride leader has been doing tours, nobody has ever been left behind. Of course, as a courtesy, please don’t leave the leader too far behind! We stop at every trail intersection to make sure people don’t get lost, at the top of every climb, and the bottom of every descent. We also take breaks as often as needed to let people catch their breath and to eat once an hour on longer rides.

Will you provide first aid if I’m hurt?

Your ride leader is not an emergency medical technician and can only render basic first aid assistance. If you need more than basic first aid, your ride leader will make sure you get the help you need from trained professionals.

Is anybody other than the XEN MTB guide joining us?

If you don’t mind, it’s a good idea to bring a trail “sweep” along with us (a person who will always stay at the back). But that’s up to you. There’s no extra charge for bringing a trail sweep with us.

Some of my buddies that want to ride with me are faster / slower than me. Is that OK?

It’s highly recommended that you ride with people who have equal skills and endurance. But as long as your buddies don’t mind, if some people want to push hard, your guide will advise you where it’s safe to sprint ahead to the next stopping point.

Your guide will always stay with the slowest person in the group. If you’re waiting longer than 10 minutes at the next rest stop, turn around and rejoin the rest of us at the back! Do that a few times, and you probably won’t be sprinting up the hills anymore.

If you miss a turn or stopping point or leave your guide behind, you may find yourself alone in the great outdoors. So pay attention!

Are There Other Fees?

Fuel Charge

A fuel charge is added to the tour price as a transportation cost. The charge is based upon the amount of fuel that will consumed from the John Wayne Airport area to our tour destination and back, cost for insurance, wear and tear, etc..  Transportation fees are non-refundable.

Shuttle Fees

Some rides require a shuttle company to drive us to the top of the mountain. In most cases, these fees are separate from the fees charged by XEN MTB.

Parking Passes, Entry Fees, Etc.

Some areas we ride in require a permit to park, entry fee, etc. In most cases, these fees are separate from what XEN MTB charges.

Electric Bikes

Can I ride an electric bike on your tours?

XEN MTB believes that e-Bikes (electric bikes) should be allowed on any trail where human-powered bikes are allowed.  However, due to over-reaching laws in California, electric bikes (those having a battery-powered motor) are not allowed in most of the areas that XEN MTB serves.   

XEN MTB does not maintain an exhaustive list of all the regulations surrounding electric bikes and will always choose the side of caution, which is that they are not allowed unless you can prove otherwise.   Bring that proof with you should you choose to ride an e-Bike.

IMPORTANT: If you choose to ride an e-Bike, and are then told to leave an area by an official representative of any government-owned or privately-owned land, even if that area that should be legal, YOUR TOUR FEE WILL NOT BE REFUNDED and WILL NOT BE RESCHEDULED. 

XEN MTB is not responsible for any legal repercussions you could suffer, including but not limited to: fines, arrest, seizure of your property and imprisonment.  XEN MTB makes no legal representation as to whether or not electric bikes are allowed anywhere.  You are solely responsible for your use of e-Bikes in every regard.

For your reference, the full text of California Assembly Bill 1096 which authorizes the use of e-Bikes of certain types in certain areas is viewable here: https://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=201520160AB1096

Can my child join you?

Yes, your child can join you on a ride that you book with XEN MTB.  There is no extra charge just as there is no extra charge for three adult guests (a maximum of four people, total).  Minors cannot ride by themselves.


Do you do shuttles?

XEN MTB does not provide a shuttle service. We use licensed and permitted third party operators throughout Southern California.
