There are
MANY F3's out there safely using either of those ^^ options successfully, and so far, we haven't seen the reports of
ANY safety concerns, failures, or even issues beyond the OEM height of the pedal being a pain in the ankle - not in what must by now be at least an accumulated few million miles of ryding by all the F3 Ryders! And then there's all the RT Ryders too, especially those with the 2020+ versions, who probably have more of a 'foot raise' concern than F3 Ryders with their OEM pedal position, but pretty much all of these Spyder Ryders either get used to the OEM pedal height or use whichever one of the pedal height change methods takes their fancy and then they basically have no more significant concerns from there on in! Neither have there been any safety issues reported about Spyders &/or any of the numerous other bikes out there running floor boards rather than foot pegs, and I'm pretty sure that not too many of any of the riders with floor boards (or pegs!) ride around with their foot raised in the air hanging poised over the pedal just because it feels as tho that's what they need to do to be quick enough to operate the brakes in an emergency - while it certainly might feel like that initially, it's just not necessary, especially if you adjust the pedal by whatever your preferred choice may be in order to reposition the pedal where you feel comfortable!! And you might ask yourself if you or anyone else you know of has ever felt the need to adjust the pedal height in their car or truck cos it didn't feel right initially, or did you/they just get on with it and now don't even notice it any more??
I will admit that the majority of those commenting here recently that I've seen have suggested that the OEM Pedal height isn't ideal, but most either simply get used to it as it is from the factory or they use one of the many methods available to fix the pedal height to their satisfaction and then they just get on with enjoying ryding their Spyder, a machine which, just by the way, has
far better braking capability than just about any other vehicle on the roads!! So much better that I'd strongly suggest you (or your wife) pay close attention to who/whatever is behind you if you ever need to stop in a hurry, cos if you do need to and there's something close behind, your Spyder
WILL be able to significantly out-brake it regardless of your pedal choices and if you do fully apply your Spyder's brakes, you need to be careful not to become the following vehicle's bonnet ornament - altho maybe not so much so if you choose to go the handbrake lever method, cos there isn't hand lever option available that I've seen or heard of yet that applies quite the same braking force as that provided by any/all of the foot operated pedal options!
So I reckon that you're probably being a little over-concerned about all this - try doing a
search by entering something like '
brake pedal' in the
Search field (up near the top right of the screen); ticking the '
Search titles only' box;
submitting the search; and then using the titles in the listed results to help you choose which threads to spend a few hours on reading - there's a
LOT of info already available here about Spyder brakes & pedal height modifications (and Spyders in general - there's not much that hasn't already been at least touched upon since the Forum started waaaay back when Spyders first came out!) including heaps of detail & discussion about how people have adjusted their pedal height; some discussion on the various options and methods of adding a hand lever for the brakes, with either hydraulic or mechanical linkages, and even some DIY methods; info on swapping the brake pedal to the other side; and a bunch of other stuff besides.
But seriously, for most new ryders/owners, the best thing you can do is get yourself some saddle time -
LOTS of saddle time!! And remember, your Spyder's brakes are pretty damn good, likely better than just about anything else you've ever experienced, especially once you get used to them &/or whatever pedal arrangements make you feel comfortable in using them! So I'd suggest that you (&/or your wife) should
Ryde More, & Worry Less - at least until you get comfortable on the Spyder and can clearly identify those things that you really need to fix/modify, rather than those things that are likely just 'different' to what you're used to?! Just Sayin'
