I was in the same situation this time last year.
I’ve had numerous Orange & Nicolai, & struggled to decide between the 2 (helius am & 5 am),and plumped for a 5 – within 1 week I regretted it!
Doing a bit of soul searching, I realised that I wanted the Nic’ but bought with my brain not my heart. I wanted something that I loved to look at, caress, be proud of, & felt unique, & what I got was an updated & sanitised version of what i’ve already had. I’ve now sold that, bought a Nic’ (cc not am by way of a nod towards using my brain not heart), & then bought a 2nd hand FR to satisfy my ‘big bike’ need/want.
In short, buy the Nicolai – they are very special, and you rarely see another out on the trails. They ride as good as anything else, but have a certain ‘something’, which makes it feel oh so special compared to the rest.
