Besv JGR Premium E-Bikes

Besv JGR Premium E-Bikes PRODUCT Congratulations! You have just purchased the ﬁnest pedal-assisted electric bicycle in the market today.
Your BESV e-bike can be pedaled like a normal bike, and it can assist you while you pedal. Be sure to read this Quick Start Guide before you start an amazing ride with your BESV e-bike.

Introduction

Pedelec (A Type of E-Bike)
A pedelec is an electrically assisted bike that provides assistance when and only when you pedal. The torque sensor located on the pedal crank bearing detects how hard you are pedaling and determines how much power the motor should provide to give you a pleasant ride. The electric motor is turned oﬀ as soon as you stop pedaling.
In most countries, there are laws regarding pedelec design and the use of pedelec. For example, the maximum assisted speed is 25 km/hr (15.5 mph) in European countries. When you are reaching the maximum assisted speed, the motor starts to reduce its power output until it ceases in order to meet the law requirement. However, with pedal-assist function oﬀ, you may be able to surpass the maximum assisted speed with your physical strength and agility.

Intended Use

For your safety and for avoiding damages to your bike, please make sure your pedelec is used according to its intended use.
BESV JGR is designed to be a gravel pedelec. Please ride your bike under suitable conditions. If you have other needs, such as downhill riding, please select other suitable bikes for your safety.
This pedelec is designed to be ridden by only one person (the rider) and does not permit carrying infant, children or animals.
Pedelec do not intend to limit the stature, perception, and mental ability of its user; however, a child under 14 years old is prohibited to ride the pedelec. (Please check your local laws; the minimum age may be higher.) According to EN regulation the maximum gross weight of the e-bike, including the weight of rider, accessories and/or cargo, is under 120 kg (264 lb). Do not exceed the allowable gross weight. It is also not designed to pull or tow another bike, trailer, or any other items via a connection system.
Notes for Cleaning
Do not use high-pressure or steam cleaning equipment to clean the bike. The steam or water jet coming from a high-pressure cleaning machine may cause damages to the bearings, bolted parts, tires or other bike surfaces and may be diﬃcult to be seen with naked eye. Water may also seep into bearings or damage the electrical parts of the e-bike system. Such damages may lead to malfunction and therefore risk of accident. Please try to keep your bike dry, and avoid using excess water t o clean it.
Use soft cloth, sponge or brush to clean your bike. Use moderate amount of neutral detergent for cleaning. Make sure there is no detergent residue on your bike after cleaning. Please do not use non-neutral detergents to clean your bike.
