Is their a particular term for "standing" while cycling, and how is it done? I've never been able to manage it, nor for that matter, flinging my leg over the saddle while the bike is still in motion, when the ride comes to an end.
Do you refer to a "track stand"?– Grigory RechistovMar 4, 2018 at 17:22
@GrigoryRechistov Reference to "bum-off-seat" in the title suggests standing on the pedals while moving, to me.– David RicherbyMar 4, 2018 at 17:56
1I read it as "BURN-OFF-SEAT" and thought someone wanted to remove the padding from a saddle :)– Criggie ♦Mar 5, 2018 at 1:12
Actually, you can only fling your leg over the saddle while you are moving: You need the movement to be able to balance your bike by steering! Only very few people manage to balance on a non-moving bike (and I'm definitely not one of those).– cmaster - reinstate monicaMar 5, 2018 at 22:36
Riding uphill while standing on the pedals is referred to 'en danseuse' in French,literally 'as a dancer' or 'like a dancer' which is a nice description. Swinging the leg over the rear wheel is something used in cyclocross and normally frowned upon by road-racing cyclists. And it may be the cause cause for an accident because the bike is less steerable and unstable in that phase. It's not major a problem if you can't do it!– CarelMar 7, 2018 at 12:33
You can use the term "posting" to describe lifting yourself off the saddle when riding over bumps/potholes. It doesn't necessarily mean standing all the way up, but rather "floating" above the saddle so that your weight is on the pedals, not the saddle. This distributes your weight a little more evenly between both wheels, which can lessen the damage to your wheels on impact.
I wouldn't expect people to know this obscure term, but, regardless of the nomenclature, it is a very important skill to learn. Many people would benefit from riding more dynamically, that is, learning to shift their weight forwards and backwards, weighting and unweighting each wheel. The idea is that when your front wheel hits a pothole, you have shifted your weight as far back as possible. Then, by quickly throwing your weight forward, you can un-weight the rear wheel as it rolls over the hazard. Not only is this more comfortable for your butt and back, it puts minimal load on the wheels for the impact, which will help keep them true longer and reduces your chance of a pinch flat.
1I've never heard posting outside of the fixie crowd, for which its a portmanteau for "pedal and coast" cos they can't coast on a fixed gear. Nothing in OP's question says fixed gear. Personally I'd call it "unweighting (the saddle)"– Criggie ♦Mar 5, 2018 at 1:14
A really good place to practice this is the short sharp plastic speed bumps common in car parks. Pick a low-to middling gear and stick in it, now try riding at a comfortable cadence in different positions: fully seated; saddle barely unweighted; heels down, weight back; etc.– Chris HMar 5, 2018 at 13:49
It can be called "standing sprint" if used by a road race bicyclist during a race/training. At MTB, it can be associated with "attack position", where one leaves the saddle momentarily (or for quite prolonged periods of time in fact, thanks @mattnz) to not be thrown out of the bike by the saddle launching the rider into space.
For regular commuters, Sheldon Brown considers the need to stand up while pedaling as a sign of a bad technique or poor bike fit:
If you find yourself standing to accelerate, on level ground, it is a sign that your gear is too high or that your saddle is too low.
Also from there:
Standing pedaling doesn't make you any faster, except in the very short run.
So, check your gearing technique and bike fit.
1MTBers us the Attack position - which requires bum off seat far more than 'momentarily', in fact its the most basic skill of MTBing to ride in this position.– mattnzMar 5, 2018 at 0:07
@mattnz, indeed, one can tell that an attack position is done out of the saddle. It did not come to my mind however, as the use and weight distribution is so different from the race sprint case. I will update the MTB part. Mar 5, 2018 at 4:25
1+1 for the comment on bike fit. You should never feel the urge to leave the saddle. Yet I daily see all those folks with way too low saddles, claiming it was "safer" as it allows them to reach the ground with their feet... Mar 5, 2018 at 22:32
1@cmaster Recently I was "forced" to use a dirt jump bike with only about 20 cm of seatpost length as my main and only bike for a month. It made me realize the importance of proper saddle height for real! Mar 5, 2018 at 22:51
It looks like you aren't asking about standing and pedalling as such, but just standing at all? And your mention of not being able to mount and dismount by raising one leg over the seat just confirms this.
It is worth buying a bike that suits your mobility and balance. Bikes traditionally aimed at women in dresses have no top tube so you can "step through" so not being able to step over is not the end of the world.
Being able to stand while cycling is just a matter of balance and practice. If you are freewheeling, holding the seat or top tube between the legs gives a lot of balance and control, but if your hands are on the handlebars it should be straightforward to stand on the pedals (or even on one pedal) and balance just fine.
Just put in practice - when sitting and travelling gently downhill (so you don't need to pedal) try standing up. You can sit down as soon as it feels unstable. Once you have perfected this, try pedalling while standing.
To answer your question, in the UK, the terms
out of the saddle or
standing on the pedals would describe the technique. If you google these terms you'll get a lot of hits.
