Opening a new shop.

Bike shops don't make money look at Cycle Repubic/ Halfords if they can't make it work who can ?

Cycle Republic was doing well, it's the fact that Tredz (also owned by Halfords) make them more money than Cycle Republic simply due to the lack of brick and mortar to maintain, so they decide to just close Cycle Republic and keep investing in Tredz to sell bicycles, while Halfords have a much diminished workshop for the bare necessity of servicing bicycles.

Selling bicycles make more money than servicing bicycles*.

It didn't end well, as customers from Tredz (and Halfords, even Evans Cycles) often come to Cycle Republic for servicing.

*as mentioned earlier, while selling bikes net a bigger profit, it's very much dependent on the market, whether servicing bicycles will always remain consistent as long the workshop is up to dates and maintain quality of workmanship.
