Hello, I am an instructor/guide at Trail Tours, and I thought I would chime in with a few points. I'm sure you can understand that just renting a bike out without ensuring the rider has the proper skills would be a recipe for disaster, and Trail Tours would not have remained in business for more than 15 years if we had not placed the safety of our customers as top priority. Insurance regulations insist that all groups have a trained staff member along with first aid training.
The instructors at Trail Tours know the Ganaraska (and other trail systems we ride) inside and out, and will lead customers at their own pace to trails that will satisfy any riding style and skill level. We are not their to nag or slow you down, but to facilitate an excellent experience and ensure you get the most bang for your buck. With hundreds of Kilometers of trails, the forest can be confusing and daunting to those who do not know it. We can take you immediately to the terrain you wish to ride.
As a long time trail rider who learned to ride as a kid by jumping in head first without any training, I can testify that a few pointers on proper off-road technique has vastly improved my riding ability, confidence and speed. The majority of seasoned off road customers that ride with us for a day leave as better riders, even though only small fraction of the day is spent on instruction.
At $240 it is really a good price, when you consider that a modern safe (used) dirt bike will cost at least $2000 and up + tax + licence (and depreciate by say $300 - $500 per year). Then you need Boots, Gloves, Helmet, goggles, Pants, chest protector, minimum investment of say $500 in gear, insurance for a strictly off road bike ranges from $200 to $500 per year, Ganaraska trail pass $125 per year, gas, say $10 - 20 per ride, lunch $10 per ride, a bike requires at least $150 - $200 maintenance per year, much more if ridden often or damaged (oil changes, tires, chains, sprockets, that is if you don't have to do engine work, wheel bearings, suspension bearings, carburetor etc.), then you need a trailer and a vehicle to haul it, a pressure washer, a garage to store it in all year, etc.
Hope to see you in the forest!
