General Info

Assembly and Fit

Correct assembly and fit are essential elements of ensuring your bicycling safety, performance, and comfort. Even if you have the experience, skill, and tools to complete these essential steps before your first ride, Senada Bikes recommends having a certified, reputable bike mechanic check your work.

NOTICE: If you do not have the experience, skills, or tools to complete assembly and operation, Senada Bikes highly recommends having a certified, reputable bike mechanic complete these procedures as well as any future adjustments or tuning.operation
NOTICE: A critical aspect of assembling your bike by Senada Bikes is securing the front wheel and checking the tightness of the rear wheel axle nuts. These mechanisms may become loose or unsecured during shipment or over time. The torque and security of all-wheel mounting hardware should be inspected upon arrival and on a regular basis. Both wheels need to be properly secured before operating your bike.

Mandatory Equipment and Use Locations
Before all rides, ensure you have all required and recommended safety equipment and are following all laws on using an electric bike in your region.

Changing Components or Attaching Accessories
The use of non-original components or spare parts can jeopardize the safety of your e-bike, void your warranty, and, in some cases, cause your e-bike to not conform with the laws of your bike.

Safety Check Before Each Ride

Always check the condition of your bike before you ride in addition to having regular maintenance performed. If you are unsure of how to conduct a complete check of the condition of your bike before every ride, you should consult a certified, reputable bike mechanic for assistance.

Electrical System

The electrical system on your e-bike offers various levels of power assistance and lighting for different operating conditions and user preferences. You must familiarize yourself with all aspects of your bike’s electrical system and check to see that it is working correctly before every ride. The front and rear brake levers contain safety power cutoff switches, which disable the hub motor’s assistance when applied, and both levers should be checked for correct operation. The throttle should provide smooth acceleration when gradually applied. If the throttle, brake lever cutoff switches, pedal assistance, or lighting are functioning abnormally, intermittently, or not working, please discontinue using your e-bike immediately and contact the Senada Bikes Support Team for assistance.

Brakes
Ensure brakes are working correctly, all braking system components are free from damage and properly secured. When you fully squeeze the brake levers, ensure neither the front nor rear brake levers touch the handlebar. Take your bike to a certified, reputable bike mechanic to have the brakes repaired if you find a problem.

Tires and wheels

Your wheels should always spin straight and must be repaired or replaced if they wobble side to side or up and down when spinning. If your wheels become untrue or the spokes loosen, which can happen with normal use, we recommend that a certified, reputable bike mechanic performs all wheel tuning and truing operations on your bike from Senada Bikes. Do not attempt to true wheels or tighten spokes unless you have adequate knowledge, tools, and experience. Ensure the tires and inner tubes are in good working condition without any visual damage and have the correct amount of air pressure. Always replace tires and inner tubes with punctures, cuts, or damage before you ride, in case of tire and component wear, and make your riding unsafe.

Quick Release Levers
There is a quick-release lever located on your e-bike for securing the seat tube. This provides convenience to the user since they allow the seat tube to be adjusted without tools. Since quick-release levers can be loosened during transportation, or accidentally between or during rides, you must regularly check to ensure these components are properly secured.

Accessories, Straps, and Hardware
Ensure all hardware is secured and all approved accessories are properly attached per the specific component manufacturer’s instructions. It is good practice to look over all hardware, straps, and accessories before each ride and if you do discover something is wrong or find something you are not sure about, have it checked by a certified, reputable bike mechanic.

Suspension, Handlebar, Grips, and Seat Adjustments
The suspension fork on your e-bike will affect the handling of the bike, you need to understand how it works before use. The suspension fork should be properly adjusted for your weight and terrain. Ensure the handlebar and handlebar stem are properly aligned, fitted to the user, and secured to their recommended torque values. Handlebar grips should not move easily on the handlebar end. Loose, worn, or damaged handlebar grips should be replaced before you ride and can be purchased from Senada Bikes. The seat and saddle tube should be properly aligned, and fitted to the user, and the saddle tube quick release should be properly tightened, fully closed, and secured before riding.

Battery Charged, Secured, and Unplugged
Ensure the battery is adequately charged and operating properly. The battery gauge on the LCD and the charge status indicator on the battery should read similarly. Ensure the battery charger is unplugged from the outlet, and battery, then stored in a safe location before you ride.
