FIIDO D4S ELECTRIC BIKE - SUSPENSION SHOCK ABSORBER SADDLE UPGRADE INSTRUCTIONS.

Описание: Ive had my fabulous fiido d4s electric bike for a year now and its a fantastic bike in every way EXCEPT one.....go over any bumps ,potholes or road humps and it gives a spectacularly uncomfortable jolt to your body almost causing you to swerve or even worse to fall off.

i had suffered enough so I trawled the net to find a solution and although there are certain suggestions, some of which are totally wrong. I decided to work a way around the problem.

There is no ready made replacement suspension seat post for the fiido d4s anywhere and this is mainly because the existing seatpost is quite a unique size and certainly not a standard replacement size,

The only answer is to fit a post shim, a different post clamp, another smaller post clamp to stop post slip and finally a shock absorber suspension post. What sizes ? You may well ask because I went backwards and forwards trying so many different fits for this bike. so many that I almost gave up. However I eventually came up with all the correct sizing to fit the fiido d4s and im passing this on to you and hopefull will help you have a much more enjoyable ride on this fantastic e bike.

Its well worth doing, my ride is fantastic now, effortlessly passing over quite big humps and potholes
without those offputting jolts.

Best of all its not a seriously expensive upgrade.costing roughly £35 if you shop around for the parts that are freely available on ebay and amazon.

Here are the instructions in print....the photos of the parts are on the video..

ITEMS YOU WILL NEED.
See video attached.

1. SEATPOST SHIM.
Size 34.9 - 31.8

2. Two SEATPOST CLAMPS. ONE @ Quick-release Seat Post Clamp 40mm & ONE bolt clamp @34.9mm

3. SUSPENSION SEATPOST SIZE
Length: 400mm
30.9 diameter

Firstly bear in mind this may not work if you are over 5ft 9ins in height because this new seatpost may be a little too low in height for you.

First remove the old seatpost by opening the seatpost clamp and drawing the post out.

You need to remove the saddle from the old seatpost,
You dont need the old saddle clamp as you will use the one on the new suspension post.

Remove the old clamp from the seatpost hole by turning the little allen screw at the back . The clamp should then withdraw from the outer post.

Fit the new seatpost shim into the seatpost hole and fit the new largest clamp on the outer post, tightening just the rear small allen screw and leaving the clamp as loose as you can without the screw falling off.

Fit the saddle to the new suspension post and tighten . You will most probably have to adjust it several times at a later stage to your desired most comfortable position.

Then fit the smaller new clamp about half way and around the new post and tighten as tight as you can. Again this will most probably have to be adjusted several times at a later stage to your desired most comfortable position.(you could use a large jubilee clip for this instead but i havnt tried that)

This is just my idea to prevent the post from slipping downwards after you have clamped it in position with the bigger seatclamp.I am heavyweight and its a common occurence because the new post is just a very slight bit undersize and otherwise it will surely slip when you are riding. ( This is why I had so many tries at this before getting all the rightish sizes for the d4s)

Now insert the post into the hole and push it down till the wraparound clamp hits the top above the other new seatpost clamp and decide if the height is near where you want . If its not loosen the wrap round clamp and raise it higher or lower until your desired height is reached. When its about right tighten it up really tight and then tighten the first seatpost clamp below it as tight as you can possibly get it . You may need to use a pair of flat pliers or a mole grip on the knurl knob to get if much more than finger tight. This is to hold the post tight in the post hole and also to stop it swivelling when riding the bike,

You should now be set to test ride the bike. Depending on your weight, the post will lower automatically on the internal spring in the post which is perfectly normal and, if youve set it right ,should then be at your desired comfortable height. If its not right do the clamp procedure again till youre happy with it. If it is right the first time youre extremely lucky ...lol.well done.

Hope this all helps. I know Its made a major difference to my comfort going over bumps on this wondeful fiido d4s electric bike .
