The I:sy from Hartje has a frame shape typical of compact bikes. The horizontal reinforcement tube above the engine can be used as a carrying handle when towing the bike into the hallway. Thanks to the folding handlebars and pedals, it takes up very little space there. The "Active Line" drive from Bosch works very lively on the 20-inch model and ensures brisk acceleration; the hub gear works well and smoothly. It is combined with a coaster brake, which older cyclists particularly appreciate; the hydraulic brakes, on the other hand, could grab a little more resolutely. The position of the battery behind the seat tube is well chosen: threaded holes on the head tube indicate that a carrier system can be attached.
