Honestly after a quick google search I'm not convinced LTO Cells are applicable for that use case. Best I found on a quick search is 80wh/kg and at a low voltage and good enough but not great discharge capacity. Even in the electrical bicycle range that's just not enough to be practical, let alone competitive.
LFP at it's peak gets you there but it's also not a great experience. The Battery needs to be too large to get you enough current to be enjoyable.
That's why the 10x (even a 3x would do it) in discharge capacity is what get's me excited. That's enough that you can use only a few cells but with enough output to be a nice experience, just with short range.
