Interesting...I have been slammed to the ground 4 times now when the front washed out on my Small LEVO Turbo unexpectedly. I have never experienced this on my analog bikes. It has typically not been on turns but rather when going over a rut or rocks. I am a very light rider (120 lbs fully loaded) and have to run a short stem as the bike is really too big for me.….
Tricky one. And I think you‘re saying you have the smallest frame. Some detail on your riding position at these moments would help but, curiously, a lot of people are not very good at reporting what they are
really doing without an opinion from others who’ve watched you…. Not you, or me, obviously ?
Some would say get a friend to video you over the sort of thing that’s changed (ruts and so on). If you could also borrow a small analogue bike (assuming you sold yours) you could video riding that at the same time/place to prove you’re riding them both the same way. Putting the camera on a tripod at ‘waist‘ height is ideal, but involves all the fuss of tripods and so on.
You might see the issue, or a friend might.
My own experience (fairly meaningless then…) is that for the reasons you give, e-bikes expose those riders who aren’t keepin their centre of gravity over the bottom bracket. And remember, achieving that sometimes involves getting your bum behind
, to the side of or at other times towards the front of the saddle, all depending on what you’re doing and the slope of the ground. It also involves keeping your heels down. And it can often involve getting your upper body nearer the bars, sometimes slightly to one side of the centre line or the other (the most obvious version of the so-called ‘attack’ position, if you subscribe to that simple phrase being used to describe many things).
@Gary (for example above) posts great advice on this general topic in practical language. Search for his advice for how and when to get more weight onto the front tyre and how to increase your courage in using the front brake (although the latter obviously isn’t the issue for you in your question today) — the topic of moving your body dynamically over the front is not just about turning (often described), it‘s also about your current dilemma too.
Good luck ?
