As a single-speed bike, Heinrich does not need gears, as this is impressively compensated for by the powerful Bosch Performance Line (65 Nm) motor and 500 Wh Bosch battery. With the maintenance-free carbon belt drive, you can reliably transfer the full power. This city e-bike has a Supernova lighting system that is fully integrated into the handlebars and seat post.
Heinrich is a clean commuter pedelec. As with all Schindelhauer models, the complex in-house development of the frame guarantees sporty cornering behaviour – something you wouldn't expect from an e-bike with a mid-drive motor. The drive unit and battery are integrated as compactly and elegantly as possible without compromising on functionality or stability.
This bike deliberately drops every gear and replaces the gearbox with torque. The AL6061-T6 aluminium frame is the base: a triple-butted tube set, forged motor bridge, multi-cell down tube, forged dropout with a slide tensioning system and the belt port designed for this drive, plus smoothed welds and a five-year warranty. This complex in-house development is deliberately shaped so that motor and battery are enclosed as compactly as possible – and it gives a mid-drive bike the sporty cornering behaviour you would otherwise expect from a race machine. Every cable disappears internally into head tube, fork and frame, keeping the lines pure.
Power comes from the Bosch Performance Line (Cruise) with 250 watts nominal output and 65 Nm of torque, supporting up to 25 km/h. The Bosch PowerTube 500 with around 500 Wh supplies the energy and is removable; display and control run via the Bosch Purion onboard computer. Because the motor works without a gearbox, the bike also stays pleasantly light and free-rolling above the support limit and with assistance switched off.
A single Gates Carbon Drive CDX toothed belt with 55T at the front, 20T at the rear and 120 teeth handles the power transfer – one fixed ratio that operates without oil, without stretch and without re-tensioning. That is precisely the logic behind this bike: where a chain drivetrain offers several ratios that can be fine-tuned on the climb, torque does the job here. With 65 Nm and a short, sporty wheelbase, the SSP also masters steep urban sections and headwind, and no shifting action is ever required. Riders who have to pull away on a gradient benefit from hub-drive simplicity – and even without gears, the hub stays uncomplicated.
The lighting is fully integrated into the cockpit and the seatpost. At the front, the Supernova Mini 2 headlight is hidden inside the handlebar; at the rear, a LightSKIN LED seatpost with an integrated tail light takes over – both powered from the e-bike battery and switched via the control unit. That keeps the bike on the safe, legally compliant side after dark without any additional accessories, and the clean-looking seatpost reads as an ordinary component.
The bike is prepared for luggage and everyday equipment without being dependent on accessories: mudguards can be fitted, and the frame geometry provides for a front rack – the classic solution for commuters who want to carry shopping, a laptop or sports gear at the front. A lock holder can be mounted beneath the top tube and a frame lock can be fitted. A child seat finds its place on the seat tube, with the tail light fitted there staying visible. The Hebie 663 FIX18 side stand is part of the equipment, and the weight in size M is just 19.7 kg – around four kilograms less than a fully equipped urban e-bike.
Equipment in detail: Formula CURA hydraulic disc brakes with 160 mm rotors, 47 mm wide WTB Horizon tyres with reflective stripes on 27.5-inch rims, Alexrims EXR25 rims with Sapim Race spokes, Schindelhauer high-flange hubs, the Miranda Delta crankset, CNC-machined Schindelhauer aluminium pedals, Satori Stealth stem, Satori Noirette handlebar, FABRIC Scoop Shallow Sport saddle, screw-on Schindelhauer grips and a hydroformed aluminium fork with tapered headset and 15 mm thru-axle.
The name of this version is made up of four parts, and each one carries a concrete technical statement.
Heinrich – the base name. The brand gives its models quintessentially German first names that read as distinctly German everywhere in the world. The naming follows a gender-specific logic with a direct technical counterpart: male names stand for the diamond frame, female names for the step-through frame. That is why Heinrich carries the closed top tube, while the female counterpart Hannah is technically identical but fitted with a swan-neck trapezoid frame.
SSP – the short form of SingleSpeed. It marks the fixed-ratio, gear-free version within a model family. Suffixes such as SSP, enviolo or Alfine in product names therefore always denote the gear type of the same basic construction, never a different bike.
Performance Line – the Bosch designation for this motor tier. Within the Bosch families, Active Line, Performance Line and CX step the performance classes: the Performance Line with 65 Nm sits above the Active Line Plus with 50 Nm and below the CX tier with 85 Nm. This gradation is what creates the price differences within the SSP range.
graphitschwarz – the colour variant. A deep, matt black that combines with the dark rims, black add-on parts and dark tyres to produce an evenly calm surface. Perlblau, titansilber and granatrot are also available in this model family.
All Heinrich variants share the same frame, the same fork, the same Gates carbon belt and the same wheel construction of Alexrims EXR25 rims with Schindelhauer hubs. What differs is the gear, the motor tier and the equipment level.
The Alfine version relies on the Shimano Alfine eight-speed hub gear and the Bosch Active Line Plus with 50 Nm; it is the fully equipped variant with frame mudguards, a frame-fixed front rack and pannier rails. The enviolo version works with the stepless Enviolo TR hub including electronic AUTOMATIQ eShift, driven by the Performance Line with 65 Nm. The Smart System generation with Kiox display, LED remote, eBike Flow app and ConnectModule preparation raises torque to 85 Nm.
On the singlespeed line, the SSP presented here with its Performance Line and 65 Nm stands apart from the SSP Active Line Plus with 50 Nm – on an identical frame, an identical belt and the same 19.7 kg in size M. That is the only difference between the two, and it is a deliberate one: the stronger motor compensates for the missing gear count without any increase in weight. Compared with the geared siblings, two advantages remain: the bike weighs around four kilograms less and is correspondingly more agile. At the same time, the SSP is the most reduced version of the family – it focuses on pure agility, short distances and a purist appearance rather than rack, mudguards and LED leather grips from the factory.
The SSP is a commuter pedelec for the city and its surroundings. At 19.7 kg it rides like a lightweight city bike and can be carried into a train, a bus or a cellar, and the short wheelbase combined with the sporty geometry makes it pleasantly direct in narrow streets, at traffic lights and through bends. The motor offsets pull-aways and headwind so masterfully that even the ride out of town works without thinking about gears. The 47-millimetre tyres on 27.5-inch wheels absorb the unevenness typical of everyday city riding, and the hydraulic disc brakes deliver predictable deceleration in the rain.
Within the family, the bike fills a clearly defined role: it is the lightest and most sporty expression. Anyone who needs a rack, mudguards, full equipment and gear range is better served by the Alfine or enviolo version; anyone who values a bike that moves through the city with no visible mechanics and minimal weight is exactly right here. Against other series from the same manufacturer, the SSP clearly separates itself: the Arthur and Antonia models are set up even more sporty and upright, the Emil is designed to be more urban and nimble, and the Wilhelm family is built as a custom and gravel bike with Pinion, Rohloff or Alfine Di2 technology for entirely different purposes.
Gender-specific variants and frame shapes are worth noting as well: Hannah is the female counterpart to Heinrich and technically identical, but relies on the swan-neck trapezoid frame and a lower step-through. On this landing page, the Heinrich is offered exclusively as a diamond frame in sizes S (45 cm) and M (49 cm); further frame sizes of the series are carried by the other product variants.
