J1649+2635 (z = 0.0545) is a red spiral galaxy with a prominent bulge that it is associated with a L$_{1.4{\\rm GHz}}\\sim$10$^{24}$WHz$^{-1}$ double-lobed radio source that spans almost 100kpc. J1649+2635 has a black hole mass of M$_{\\rm BH} \\sim$ 3--7 $\\times$ 10$^8$M$_{\\odot}$ and SFR$\\sim$ 0.26 -- 2.6M$_{\\odot}$year$^{-1}$. The galaxy hosts a $\\sim$96kpc diffuse optical halo, which is unprecedented for spiral galaxies.
