I can't see the appeal myself other than the low maintenance
-Nearly £185 cheaper than the cheapest brommie
-Quicker folding (10 seconds vs 15)
-Requires little maintenance
-No dirt from brakes or drivechain
-Much lighter than a brommie - 10kg Vs 12kg (cheapest brommie)
-Bit of suspension in the saddle
The brommie is definately the more versatile bike, but the Strida is excellent at what it does. Just a pity about the handling problems of the earlier Stridas.
