Unboxing a new e-bike is exciting, but setup can feel frustrating and overwhelming. Take a breath, because you are about to see how simple it really is. This friendly guide walks you through Riding Times Z8 front wheel installation, with safety checks and quick fixes included.
Quick answer: Your Z8 or Z8 Pro arrives about 85% pre-assembled, so the front wheel is one of only a few jobs left. Place the wheel in the fork with the disc brake on the left, centre the axle and fasten the nuts, then spin the wheel and squeeze the brakes to check everything. Most riders finish in a few calm minutes, and our support team is always ready to help.
What You Need Before You Start
A little preparation makes the whole job smoother. Clear a flat space, switch the bike off, and remove the battery before you touch anything. If you are new to handling lithium batteries, this official lithium-ion battery safety guide is worth a quick read.
Everything else you need is already in the accessory box that came with your bike.

Riding Times Z8 Front Wheel Installation, Step by Step
Riding Times uses an axle-and-nut design for the front wheel. Follow the steps below, and use the official video whenever you want to see it in action.
Step 1: Keep the bike steady and upright
Stand the bike upright and make sure it cannot tip over while you work. Avoid laying it flat on its side, because the disc brake rotor is delicate and can bend under the weight. A wall, a stand, or a helpful friend all work well.
Step 2: Find the correct side
The front disc brake must sit on the left side of the bike. This is the most important detail, because the rotor has to line up with the brake caliper on the fork. If the rotor ends up on the wrong side, the front brake simply cannot work.
Step 3: Centre the axle
Loosen the nut on each end of the axle. Then slide the axle until the wheel sits in the middle, with about 22.5 mm of thread sticking out on each side. The official diagram shows a lock nut next to the hub on both sides, so check the measurement on each side before moving on. Taking this minute now saves you from a crooked wheel later.
Step 4: Place the wheel into the fork
Lift the wheel into the suspension fork and guide the rotor gently between the brake pads. Let the axle settle fully into the slots at the bottom of the fork. Wiggle it a little if needed, but never force it.
Step 5: Fasten the nuts evenly
With the wheel seated in the fork, thread the nuts on and fasten them firmly. Tip: tighten a little on one side, then the other, so the wheel stays centred between the fork legs.
Step 6: Confirm the rotor is centered in the caliper
This step protects your brakes, so please do not skip it. Look at the front disc and check that it sits centered between the brake pads, with an even gap on both sides. Spin the wheel by hand and listen for any rubbing. A rotor that rubs can overheat and reduce your braking performance, so a wheel that merely spins freely is not enough. If you see or hear contact, loosen the nuts, re-seat the wheel, tighten both sides evenly, and check again. New brake pads also need a short bedding-in period, so brake early and gently during your first rides.
Step 7: Fit the headlight and front fender
Once the wheel is secure, attach the headlight to the suspension fork with the 4 mm hex wrench. Next, place the front fender over the wheel and fix it to the fork with the hex wrench and open-end wrench. Finally, secure the fender support frame on the left and right sides of the fork. Fitting the fender last gives you room to adjust the wheel first.

Z8 vs Z8 Pro: What Is the Same and What Differs
Good news: the front wheel installation is the same on both models. The main difference is the battery setup, which changes the weight and range.

Your Two-Minute Safety Check After Installation
Before your first ride, run through this simple checklist.
- Spin the wheel. It should turn freely without rubbing or wobbling.
- Squeeze both brake levers. The front brake should feel firm, and the bike should cut motor power when you brake.
- Check the nuts. Nothing should move when you try to shake the wheel gently.
- Look at the gap. The wheel should sit centred between both fork legs.
- Check the fender. It should clear the tire with no scraping sound.
If everything passes, you are ready to roll. Always follow your local e-bike rules and wear a helmet.

Frequently Asked Questions
How long does Riding Times Z8 front wheel installation take?
Most owners finish in a few calm minutes once the tools are laid out. Take your time with the centring and tightening steps. A careful job matters more than a fast one.
Which side does the disc brake go on?
The disc brake rotor must sit on the left side of the bike. This lets it line up with the brake caliper on the fork. If it is on the right, the front brake will not work.
Does the Z8 Pro use the same front wheel steps as the Z8?
Yes, as far as the official guides show. Riding Times lists the same front wheel video under both the Z8 and the Z8 Pro, and both use a 20 x 4 inch front wheel. If your bike looks different, check the video or contact support.
My front brake rubs after installing the wheel. What should I do?
Loosen the axle, re-seat the wheel so the rotor sits centred in the caliper, and tighten both sides evenly. If the rubbing continues, adjust the brake or contact support. We are happy to guide you.
