How to Assemble Engwe C20 E-Bike?

Although this assembling guide is made on Engwe C20 Pro, the same principles apply to Other Engwe e-bike models like C20 and EP-2 Pro too.

First of all, check that the package is complete and you have all the items listed above. Also, make sure that everything is undamaged.

It may happen that during the transport, something is been damaged.

Then I would suggest reading the assembly guide. It’s quite thorough but it has some shortcomings. But no worries. With the help of this article, you can easily assemble the bike.

Step 1 – Remove Cushions

Cutting a strap that is holding a softening cushion around an e-bike.

Firstly, let’s remove all those cushions around the bike.

The easiest way to remove those cushions is to use scissors or a knife.

Be careful when cutting those straps. You don’t want to damage any cables.

Pro Tip! After the cushions are removed, fold the bike and remove the battery. Connect it to the charger and plug the charger into the wall. You can charge the battery while you assemble the rest of the bike.

Step 2 – Attach the Handlebar

For me, it took some time to figure out how it should be done. In reality, it’s quite easy.

You can find the upper part of the handlebar already connected to the bike through the cables. Firstly, take the handlebar subassembly stem and attach it to the upper part of the handlebar.

Secondly, you have to fold the handlebar from the quick release. Then you can see there is a hexagon screw that has to be tightened after you attach the handlebar stem to the bike.

Make sure the fork is pointing forward and orient the handlebar accordingly.

Step 3 – Install the Front Light

Installing the front light

Installing the front light is quite straightforward.

Just use those screws that are mounted to the light.

When installing the light, you need to use a wrench from one side and a screwdriver on the other side.

Step 4 -Install the Front Wheel

Before you can install the front wheel, you need to remove the transportation bolt from the fork.

The transportation bolt on between the fork.

Then I would suggest you turn the bike upside down. Be careful to not damage the display.

Next, just attach the wheel in the correct position. Make sure the brake disc goes in between the brake pads.

After that, take the quick-release skewer. It has a lever, 2 springs, and a nut. Note that the springs must be positioned so the narrower sides are inside.

Remove the nut and one spring and insert the skewer from the disc’s side.

Then from the other side, attach the spring followed by the nut.

Then tighten the nut until the lever becomes firm to close.

Step 5 – Install the Seat Post

Next, let’s attach the seat post. It’s probably one of the easiest steps.

Just place the seat post with a saddle where it belongs and tighten it with a quick-release lever.

Step 6 – Install the Pedals

The pedals of an Engwe C20 Pro electric bike.
To find out if the pedal is left or right, look for the mark on the bottom of the pedal bolt.

Although the pedals look the same, they are not.

Make sure to install each pedal to the correct side. Both pedals are marked, so you know which one goes right and which one goes left.

The right pedal or drive-side pedal must be threaded clockwise. Start the threading with your hand and then tighten with a wrench.

Repeat this on the left side but the threading must be done counterclockwise.

Good job! Basically, the bike is now assembled. As I promised, it was not difficult at all!

Before you can go for the first ride, you just have to wait until the battery is charged.

Additional Safety Measures

While the battery is still charging, you should check some details on your bike. You can take the bike outside without the battery.

  • Check all the tightening points of the bike.
  • Adjust braking pads accordingly. Make sure the wheels are running freely and there is enough stopping power.
  • Adjust the derailleur if needed. It may happen during the transport that the derailleur moves out of place.

When I was testing my bike for the first time, I discovered that some gears were off.

I took the bike to the local service and they fixed it with ease. They also checked other moving parts.

If you don’t feel like an adequate mechanic, I suggest you do the same. It doesn’t cost you a lot and you can rest assured that everything is adjusted accordingly.
