I had a chance to visit Japan Bike Show the other day. Toxic Works from Shizuoka city kindly share with us their space for Thumbster at the booth. Thank you, Mr Mamiya!
Across our booth, Yoshikawa Mfg had a booth for what they are known for, brake levers, brakes and etc. There was one product which caught my eyes. It is a brake lever but not controlled by fingers but palm. It is called Palm Brake Bar.
These are good for children whose fingers cannot reach brake lever or elder people whose grip are weak. Also good for wheelchair.
