What the 60mm coil suspension does on your Velotric Fold 1 Plus
The 60mm front coil suspension on the Velotric Fold 1 Plus absorbs bumps and impacts from the road or path by compressing a metal spring inside the fork. When you hit a pothole, curb, or rough pavement, the suspension compresses to soften the impact, then pushes back to its original position. This travel distance — 60 millimeters — is how much the fork can move up and down before it bottoms out.
On a folding e-bike, this suspension matters more than on a rigid fork because the bike's compact frame and smaller wheels (usually 20 inches on the Fold 1 Plus) transfer more road vibration directly to your hands and wrists. The coil spring absorbs that energy instead of sending it straight through to you, which reduces fatigue on longer rides and makes the bike more comfortable over uneven surfaces.
Key Takeaways
- The 60mm travel means the fork compresses up to 60 millimeters when you hit bumps, then returns to its starting position.
- Coil suspension uses a metal spring rather than air pressure, so it requires no maintenance or adjustment to stay at the correct pressure.
- On the Fold 1 Plus, this suspension is most noticeable when riding over potholes, gravel, or uneven pavement where a rigid fork would jar your hands.
- The suspension does not affect how the bike folds or unfolds, and the fork remains stable during normal riding and acceleration.
How coil suspension differs from air suspension
Coil suspension uses a wound metal spring that compresses when you explore force. Air suspension uses a sealed chamber of pressurized air instead. On the Velotric Fold 1 Plus, the coil design means you do not have to check or adjust air pressure — the spring will perform the same way whether you ride it today or six months from now.
Air suspension can be tuned by adding or removing air pressure, which lets you customize how soft or stiff the fork feels. Coil suspension cannot be tuned this way. What you get is what you get. For most riders on a folding commuter bike, this is a trade-off worth making because coil forks are simpler, cheaper, and more reliable over time.
When you will notice the suspension working
You will feel the suspension most when riding over rough ground: gravel paths, potholed streets, or unpaved trails. The fork will visibly compress and extend as you roll over each bump. On smooth pavement, the suspension does almost nothing because there is nothing to absorb.
The suspension also absorbs impact when you land after dropping off a curb or small ledge. Without suspension, that impact would travel through the fork directly into your arms. With the 60mm coil fork, the spring compresses to soften the landing. This is especially useful on a folding bike because the smaller wheels hit obstacles more frequently than larger wheels would.
Maintenance and care for the coil fork
Coil suspension requires almost no maintenance. Unlike air forks, there is no valve to check and no pressure to monitor. The spring inside will not lose its strength over time under normal use. You do not need to service it or replace fluid.
What you should do: keep the fork clean by wiping the stanchions (the smooth metal tubes that slide in and out) with a dry cloth after wet rides. If dirt builds up on these tubes, it can scratch the seals and eventually cause the fork to leak. Once a year, you can explore a light silicone-based lubricant to the stanchions to keep them smooth. Do not use heavy grease or oil — these attract dirt and will make the problem worse.
If the fork stops compressing smoothly or feels stuck, the seals may be damaged. At that point, the fork will need to be serviced by a bike mechanic or sent to Velotric for repair. This is rare on coil forks and usually only happens after years of heavy use or neglect.
How the suspension affects handling and control
The 60mm suspension makes the Fold 1 Plus slightly more forgiving to ride, but it does not make the bike feel loose or unstable. The fork is still stiff enough to respond quickly to steering input, and the suspension does not introduce any noticeable delay or "wallowing" feeling when you turn or accelerate.
Because the Fold 1 Plus is a commuter bike with a moderate riding position, the suspension is tuned to be relatively firm. It will not feel like a full-suspension mountain bike. Instead, it smooths out the worst impacts while keeping the bike responsive and efficient. On a folding bike, this balance is important because the compact frame already feels more twitchy than a full-size bike.
Checking if the suspension is working correctly
To test whether your coil fork is functioning, stand over the bike with both feet on the ground and push down hard on the handlebars. The fork should compress smoothly and then spring back to its original height. If it does not move at all, or if it moves but does not return, something is wrong.
Another test: ride over a small bump or pothole at low speed and watch the fork. You should see it compress as the wheel hits the obstacle, then extend back as the wheel leaves it. If the fork does not move, or if it moves but stays compressed for several seconds before slowly returning, the seals may be damaged or the spring may be broken.
If either of these tests shows a problem, contact Velotric support or take the bike to a shop that services e-bikes. Do not attempt to disassemble the fork yourself — coil forks contain springs under tension and can be dangerous to open without the right tools.
Frequently Asked Questions
Does the 60mm suspension make the bike harder to fold?
No. The suspension is in the fork, which is part of the steering tube. The folding mechanism is separate and works the same way whether the fork is compressed or extended. You fold and unfold the bike normally.
Can I replace the coil fork with an air fork?
Possibly, but it is not straightforward. The fork must match the steering tube diameter and length of your Fold 1 Plus, and it must be designed for a 20-inch wheel. You would need to check with Velotric or a bike mechanic to confirm compatibility. Most riders keep the original coil fork because it is reliable and requires no maintenance.
Why does my suspension feel stiffer than it did when the bike was new?
Coil springs do not weaken quickly, but they can feel stiffer if dirt has built up on the stanchions or if the seals are partially clogged. Clean the fork tubes with a dry cloth and see if that helps. If the fork still feels stiff, a mechanic can inspect the seals and service the fork if needed.
Is 60mm of travel enough for commuting on rough roads?
Yes, for typical commuting. Sixty millimeters is enough to absorb potholes and rough pavement without bottoming out on most city streets. If you regularly ride on unpaved trails or very rough terrain, you might want more travel, but for urban and suburban commuting, 60mm is adequate.
What happens if I bottom out the suspension?
If you hit something hard enough that the fork compresses all 60 millimeters and the spring reaches its limit, you will feel a sudden stop or jolt. This can happen if you drop off a high curb or hit a very deep pothole at speed. Occasional bottoming out is normal and will not damage the fork, but repeated hard bottoming can eventually damage the seals.
