The Boar Explorer is a highly intelligent electric bike made to deliver A-class performance on almost any type of terrain. It comes with a smart LCD which gives all minute details about your bike. You can even set a passcode, and the bike will not start until you enter the password. The Boar has a powerful 500W motor with a torque sensor to assist you in pedaling. 

  • Pedal Assist System: The incredible torque sensor analyses how hard you are pedaling and accordingly matches the power with it. You can ride long distances without putting in less physical energy. 
  • Coloured LCD and USB Jack: The smart LCD screen fit in the middle of the handlebar displays all the vitals to help you keep up with the performance of your ebike. It comes with a USB jack so that you can listen to songs while riding. Also, it provides additional security, as you can set a passcode to lock the bike. 
  • Thumb Throttle: The handlebar is equipped with a thumb throttle to engage in the motor power. The more you push, the faster the bike will go. 
  • Long-Range Battery: The Samsung lithium-ion 48V 20AH battery is powerful and lasts long. It also has a battery capacity indicator on it that reflects the battery life. 

The Boar Explorer is a uniquely designed bike with a new style cockpit. The bike comes with two battery options that you can choose as per your riding needs. It originally comes with a Samsung lithium-ion 48W 14Ah battery that is powerful and lasts long. But you can upgrade it to a 48W 20AH 5000 mAH cell size battery if you prefer to ride the bike for long distances. The powerful 500W hub motor has a torque sensor and an on-demand throttle. 

The Boar is the pickup truck for bikes because it delivers amazing performance even with heavy loads. The bike is equipped with Maxxis Colossus 27.5” x 4.50” fat tires that provide great balance on rocky and sloppy terrains. In addition, the 27.5” X 100mm rims provide great suspension and inertia when riding through rocky terrains.

The 6061 aluminum alloy frame is durable and rust-resistant. The frame can bear extreme weather conditions while still keeping its strength. The battery is kept in a case that is fixed to the frame. You can charge the battery while it is in the case or even take it out. The casing of the battery saves it from any external damages. 

The smart LCD screen in the middle of the handlebar displays necessary riding information such as time, distance, battery percentage, etc. You can use the information to analyze your bike performance. The battery runs long, but you can plan your halts accordingly with how long it will run. In addition, the bike is equipped with rear and front lights to assist you in night riding.
