Replace front chainring to a bigger on Radrunner
Litepro Road Folding Bike 130BCD 45-58T Chainring Bicycle Chainwheel Bolts CNC
"But the key is to pick an afternarket chainring with 130mm BCD (bolt circle diameter), designed for 3/32" chain. You'll likely also need a new set of "standard length" bolts. since the stock ones on the Runner are longer to accommodate the inner and outer guard rings.

"Bought an extra set of standard bolts, and kept the Rad bolts together with the rest of the stock components."
"It made a small, but noticeable difference. You'll need a shorter (standard length) bolt set. I added an extra inch of chain, but it wasn't absolutely required. Now that my top speed is "unlocked"....I might go with a 58T." - K. Hunter

"Underside of bolt head to end of threads is about 8mm, but a bolt 10mm long should also work, provided the mating "nut" is short enough to not bottom out."
