Our partner in Hue is called Kim Thiên and he is a trustworthy English speaking mechanic.
Once you have brought a bike from us you will be able to get a free service from here up to the value of 200k VND. (not including an oil change.) He will check all of the bike and give you an honest evaluation of what needs to be done. If extra work is needed then you will need to pay for anything over the first 200k VND.
When you arrive for the free service you can ring us if you need our help but the mechanic speaks excellent English we you should be able to explain and communicate anything that you need.
