The BigRig ADV is a monster!! It is a workhorse!! It is basically a tandem 4 wheel Bicycle with an electric assist motor. It runs off two car style batteries(they are actually marine grade). Their charge seems to last forever! Either Or both riders can pedal together or independently as well as the motor is capable of pulling the whole load with minimal pedaling!! The motor as on almost all my ADVs really helps assist and train the dogs to run as well as alleviate the load so essentially the dog is just running, which is great for the younger pups as to not inhibit proper bone and growth development!!
I have totally re-engineered this hydraulic. I have installed hydraulic brakes as well as the regular mechanical brakes. This beast eats brakes because of the weight and hilly terrain I run it on. I also have 3 different Parking Brakes to prevent the dogs from pulling it when we stop. I have put a Sacco Cart style pull bar on the front end so it can be pulled by three dogs side by side and they are hardwired in!! I will be expanding that to make it a 4 dog tow bar apparatus on the front end in the near future!!
On the sides I have added bars which can accommodate “Springers” or the “U” Shaped dog attachments I have mentioned. I have also equipped it with a cooler and battery operated pump driven Misting System to make the dogs “SWEAT” for the warmer weather months. In addition there is a canopy which attaches easily to shelter me from wet weather!!
