I run the London Bike Studio.
We are a small independent bike shop, training and employing young people and women. We are hiding behind the High street and have been here since 2017. We also are the best reviewed Bike shop in Hackney

You can book a slot using our online booking system at www.londonbikestudio.org . You can book per time if you are not sure what your bike needs and we can assess the bike and amend the booking when you drop the bike over. 
You can also check out insta for social and sporty rides. And yes, we have a really lovely puppy to entertain you while you are here.
