While the need to replace the rear hub motor is rare when using a Bafang 750 watt rear hub motor, it is a part that can fail due to a variety of reasons. The good news is that replacing a rear hub motor in our R750 series bikes is a fairly straightforward job that can be completed in under 30 minutes by a bike mechanic. Please see the video above for step-by-step instructions on what steps are required to complete this project.

All of us here at M2S Bikes would like to thank you for your recent purchase of one of our bikes. We want you to get out and enjoy your bike as quick as possible so when you receive your bike, it will come 90% assembled. The only parts you need to install are the handlebars, front wheel, seat and pedals. Always remember, before your first ride you need to inspect your entire bike, ensuring that all screws and bolts are tight and that other items are set-up properly to give you a safe and comfortable ride.
Please refer to the rest of the videos in the series on how to properly set-up your bike.
Video Transcript: Your electric bike comes with a powerful Lithium Ion battery that should provide years of riding enjoyment if cared for properly. In this video, we’ll walk through the steps you’ll need to take to charge your battery and properly care for your battery.
You can remove the battery from the bike by using the key on your bike and pulling the battery out toward you. Please take care not to drop the battery as this could damage the cells inside the battery case. To charge the battery you will want to plug in the charger that came with your bike to the battery first and then plug it into the wall.
Your charger will show the state of charging through the use of an LED light that shows red when charging and green when fully charged. Charging generally takes around four to six hours to complete.
If you’d prefer to charge your battery while the battery is still on the bike, that’s perfectly fine as well.
In general, the batteries should be topped off after each ride to get the most life out of the batteries. The battery has an onboard Battery Management System that prevents the battery from discharging below 30 percent during a ride, so when the display shows the battery is empty it has a 30 percent charge remaining, which helps prevent damage to the battery by discharging too deeply.
If your battery runs out during a ride, it’s important to try and limit the use of the battery until you’re able to get it charged back up again as using the battery once it has reached the 30 percent thresh hold can cause permanent damage to the battery and result in shorter rides in the future.
One important thing to keep in mind is that after a long ride the battery may be warm from use. If the case feels warm to the touch it’s a good idea to wait until the battery cools down before beginning to re-charge.
Like all lithium ion batteries, it’s important to keep the batteries cool, which means not storing them in direct sunlight on a hot day. We also recommend not storing your batteries in cold conditions as this will deplete the charge on the battery and could cause the battery to dip into the 30% reserve and cause damage to the battery.
When storing the battery for longer periods of time, it’s a good idea to leave the battery at about 75% charge. Over time the battery will slowly discharge naturally, so it will need to be re-charged every 3 months in order to prevent it from discharging below the 30% safety zone.
I hope this video has helped provide more insight about the proper care of your battery. If you have any questions, please email email@example.com.

Video Transcript: When you receive your bike you will notice that your pedals will need to be installed. To install your pedals you will need either an allen wrench or a crescent wrench depending your style of pedal. Your pedals are either marked with a L or R indicating which crank arm they need to be installed on. It’s very important that you grease the threads of your pedals before installing them. This will ensure that the pedal are easy to remove in the future. Start by lining up the threads and hand tightening the pedal into the crank arm to make sure that you are properly lining up the threads properly. Once you’ve got the pedal started, you can then use your allen wrench or crescent wrench to finish the job. Remember that when installing your left pedal, you are going to tighten the pedal spindle in a counterclockwise direction. When installing your right pedal, you will tighten the spindle in a clockwise direction. Once you have you pedal tightened in the crank arm, apply some substantial leverage to finish off the job of tightening your pedal.

Your full suspension bike includes an air suspension shock that needs to be adjusted to your weight for optimal performance before you ride.
To adjust the shock to your weight, you need to use a shock pump made specifically for use on bike shocks as using other pumps can damage your shock. These types of pumps are available at your local bike shop or can be ordered online.
Generally speaking, you want to start by adding 70 percent of your weight in PSI to the shock. For example, if you weigh 180 pounds you’ll want to start by adding 125 psi to your shock.
The next step is to test the sag on your shock by fully weighting your bike. You do this by sitting on your bike, not bouncing. You will want to move the O ring on your shock to the top in order to measure the sag once weighted.
What you are looking for is the O ring to move between 15 and 30 percent down your shock after weighting it. 15 percent would be an ideal starting point for rides on technical off road terrain, while 30 percent is best for a softer ride. You’ll need to customize these settings based on your weight and riding style.
If you find your shock bottoms out when riding you’ll need to add pressure to prevent this from happening.
On our full suspension bikes with the Bafang Max motors you’ll notice the shock has two air chambers. The lower chamber is the negative chamber designed to soften a hard bottom out of the shock after a big jump or drop. We recommend starting at 125 psi and adjusting as needed.
For the best performance, we recommend taking your bike to a local bike shop and working with a bike fit specialist for a professional setup to give you the best riding experience.
