Well, I've been contemplating getting getting an electric assist (one of the bionx systems to be exact) for a little while now; the only thing is the bike I would fit it to is a Trek 7300 hybrid (it has suspension on the front forks). Would this work? I'm not sure if it's too 'heavy' (although it is pretty light for bikes that size) or if the suspension would slow it down? I have two other road bikes that I use to commute with as well, I tend to use the road bikes for longer commutes and hills (as well as just for fun), and the hybrid for shorter commutes (it's great for rougher terrain and weather). So I was thinking that with the assist motor I could use the 'heavier' of my bikes (the hybrid) for longer commutes (and tackling hills, as sometimes my entire commute 'there' is up a hill) but get the comfort of the hybrid. Any thoughts or advice? Thanks!
