Found 11th Oct 2017
Update --> thanks to Thar for pointing out that this deal is actually running until 18/10/17. Full details here. To celebrate world mental health awareness day the refundable deposit has been dropped from £29 to £2 when you first register before 23:59 on 11th October 2017. The discount seems to be automatically applied and makes these brilliant bikes much more accessible for those who might be thinking twice because of the somewhat large initial outlay. The above was initially taken from an MEN article but it appears the £2 deposit scheme is actually running until next week.
