Firstly, a huge thank you to Pein Gear for providing a prototype of their pedal mount for testing and review. I understand an improved version of the pedal mount is already being worked on so no doubt they will have more interesting mounting solutions to show the community in the near future.
The package arrived safely after only 4 days in transit from SK to NZ. Neatly wrapped in cling-film with a small bundle of fittings tucked inside one of the rails.
Some very minor scuffing in the powder coat on a couple of pieces during transit but otherwise all parts arrived without any damage.
Parts laid out, left to right: 1 x chair stop rail 2 x right angle extensions 2 x side rails for pedal mount 2 x base rails for pedal mount Packet of fasteners
Close up of the pre-installed threaded barrels.
The pedal mount pieces have channels cut which allow for almost complete freedom in positioning pedals forward/back or adjusting the angle or horizontal position for offset and asymmetric mounting. The finish is good quality with plastic end caps or folded ends and threaded barrels pre-installed.
All required fasteners are included along with an allen key with a ball head - a nice addition since many suppliers don't provide tools.
8 x Cap head M4x60; washers - for connecting pedal base rails to the side rails
6 x Cap head M4x15; washers - for connecting the right angle extensions
4 x Cap head M4x20; washers; nuts - for attaching pedals to base rails
4 x Button head M6x20; washers; nuts - for attaching pedals to base rails
Fixing the pedals to the base rails is very simple - the most difficult part is getting it centered correctly. I did end up swapping out 2 of the M4x20 screws for some spare M4x30s I had as the provided screws were not long enough to pass through the MFG base with sufficient thread for the nuts on the underside.
As can be seen in this image, I still need to swap the remaining 2 M4x20 screws - the nuts are threaded but only by about one 1/2 turn.
As shown here, the pre-cut channels mean that as long as they have suitable options for screw mounting, the base rails will fit virtually any pedal system available. Although the obvious intention is to fix pedals at 4 points, if only 2 points are used on a diagonal, then the pedals could be twisted to provide an offset mounting. The pre-cut channels also make asymmetric mounting an easy option.
Even in this state, the mounting system improves the footing of the MFG pedals as they will no longer rock sideways if uneven pressure is applied.
The side rails are attached with 4 x M4x60 screws on each side which pass through the pre-cut channels to the threaded barrels in the ends of the base rails.
As with the base rails, the channels allow for wide range of movement forward and back to fine tune the leg room required.
Attaching the right angle extensions is simple enough. Mostly. Being a prototype without instructions I managed to cock it up the first time and was wondering why the holes didn't align properly until I double checked the reference photos Pein Gear had posted previously. Once I had myself round the right way, 2 x M4x15 bolts on each side fit into the threaded barrels on the pedal mount side rails. Pein Gear also suggest you can opt to use a single screw on each side which would allow for the extensions to hinge and be folded up somewhat. I will set this up for some additional photos later.
Fully assembled with the chair stop rail in place. This is held with a single M4x15 screw on either side into threaded barrels. The right angle extensions have 6 holes pre-drilled at 20mm intervals which allows for a good range of lengths for leg room - fine tuning this length is done by adjusting the pedal mount on the side rails as mentioned above.
Completed mount in place after testing for length. Excuse the birds nest. Initial impressions are very good. The prototype is well made and once assembled, the pedal mount is rock solid. The right angle extensions are a bit more flexible due to their length but this is only noticeable when moving the frame as a complete unit. When sitting at the chair and using the pedals, the whole frame remains rigid in place. On a hard surface such as a timber floor there is the possibility of some lateral movement but this could most likely be mitigated with some rubber pads. I have only tested out the new setup briefly but so far, the frame does exactly what it sets out to do - holding the pedals at a fixed distance from the user and preventing them slipping when force is applied. After sinking some more flight hours into it, I'll prepare some more detailed thoughts on how well it holds up.
