(Solved) [1.16.4] Modifying player speed based on Armor

I'm trying to make a set of armor that makes the player 50% faster for every armor piece they're wearing. But first I needed to be able to change the player's speed in general. So I made a simple event handler that speeds the player up every tick: 

@OnlyIn(Dist.CLIENT)
    @SubscribeEvent
    public static void onPlayerTick(TickEvent.PlayerTickEvent event) {
        if (event.side == LogicalSide.CLIENT) {
            event.player.abilities.setWalkSpeed(1f);
        }
    }

This works and it gives the player an insane speed boost without any conditions. What's confusing me is that PlayerEntity#abilities#setWalkSpeed() doesn't work anymore as soon as I add any logic to the handler. It doesn't even need to influence the method call. here's an example that doesn't work anymore:

@OnlyIn(Dist.CLIENT)
    @SubscribeEvent
    public static void onPlayerTick(TickEvent.PlayerTickEvent event) {

        if (event.side == LogicalSide.CLIENT) {

            PlayerEntity player = (PlayerEntity) event.player;
            float walk_speed = player.abilities.getWalkSpeed();
            float speed_bonus = 0.1f;
            for (ItemStack stack : player.getArmorInventoryList()) {
                if (stack.getItem() instanceof DynamoCoreArmorItem) {
                    speed_bonus += 0.05f;
                }
            }
            System.out.println(speed_bonus);

            event.player.abilities.setWalkSpeed(1f);
        }
    }

As you see all I did was add some code before calling PlayerEntity#abilities#setWalkSpeed(). The call itsself is exactly the same as before. But for some reason the second example doesn't work.

There are no errors. 

Can anyone explain this to me?

            event.player.sendPlayerAbilities();
        }
    }

I already tried this. Just as in the code shown in my second example, the setWalkSpeed method call doesn't work when I add this line of code.

you also can try to use an AttributeModifier (Attributes#MOVEMENT_SPEED), use the ArmorItem as an example
or try to manipulate the player's motion, but that's tricky

I now solved it using Attribute Modifiers as Luis_ST suggested. this is my implementation:

@SubscribeEvent
    public static void onLivingArmorEquip(LivingEquipmentChangeEvent event) {
        if (!event.getEntityLiving().getEntityWorld().isRemote()) {
            LivingEntity living = event.getEntityLiving();
            living.getAttributeManager().createInstanceIfAbsent(Attributes.MOVEMENT_SPEED);
            ModifiableAttributeInstance attribute = living.getAttribute(Attributes.MOVEMENT_SPEED);

            for (AttributeModifier modifier : attribute.getModifierListCopy()) {
                if (modifier.getName().equals("dynamo_speed")) {
                    attribute.removeModifier(modifier);
                }
            }

            for (ItemStack stack : living.getArmorInventoryList()) {
                if (stack.getItem() instanceof DynamoCoreArmorItem) {
                    attribute.applyNonPersistentModifier(
                            new AttributeModifier("dynamo_speed", 0.2f, AttributeModifier.Operation.MULTIPLY_TOTAL));
                }
            }
        }
    }

The PlayerEntity#abilities method could've also interferred with other mods so I'm glad that it worked this way.
