Lapierre Introduces the GLP III 12

The third generation of the Gravity Logic Project is here.

A unique concept since 2017 - an idea for a concept bike, that exceeded our expectations. The Gravity Logic Project began as a desire to do things differently, to break with current codes, and to demonstrate our capacity for innovation through design. The idea of repositioning the mass gave rise to a truly unique concept, now in its 3rd generation.


"Since the introduction of the Gravity Logic Project concept, the first 2 generations of GLPs have largely demonstrated their superiority both in terms of competition and with consumers. We had to push the concept even further in order to continue to aspire to the first places of the podiums. This third version of the GLP is even more capable and resistant, while being more powerful and enduring thanks to the new Bosch Smart System CX-R coupled with a 725Wh battery. Aesthetically the GLP III keeps the philosophy of the GLP, but at the level of the handling, I am going to surprise you again!'' - Nicolas Vouilloz

Spirit & Philosophy of the 3rd Generation GLP

Despite the 50% increase in battery capacity, we were keen to retain the GLP’s specific and unique design for rapid visual identification, thanks to the
positioning of the external battery. With the evolution of e-bike riding practices and market needs, the GLP III is logically turning more and more towards the enduro, pure-performance and competition segments. From 140 mm of suspension travel in 2017, the 3rd generation GLP now offers 170 mm for both competition and bike park use, thanks to a longer shock absorber stroke (65 vs. 60 mm previously). The frame’s specific asymmetrical design and the demands of more extreme use led us to completely rethink the frame.

Stay light and responsive, yet stiffer and more robust for e-enduro use.
To achieve this, the new GLP III is built with our best UD SLI carbon construction. Reinforced with IM/VHM fiber to maintain rigidity and dynamism, the weight of the bare frame is just 3.3 kg (size M). The use of more unidirectional IM and VHM carbon fibers, as well as a new simplified design with only a two-part mold around the motor/battery block and a new rigid mandrel, result in a better overall finish. The new frame design also focuses on cooling the engine block, with more ventilation and redirection of air to the motor, to improve performance. While the frame is 100% UD SLI carbon, the new connecting rod and extender are made of aluminum alloy.


Suspension, at the heart of the project.
Even with mixed 29/27 wheels, the GLP III had to be a perfectly balanced mountain bike in terms of front and rear suspension. To achieve this, the geometry was adapted for single-crown fork lengths with 170 mm of travel. Above all, work was focused on the rear shock absorber and its anchoring points. Specified at 205x65 mm (vs. 60 mm on the previous generation), the GLP III frame is now compatible with all shock absorber types on the market, whether air- or coil-sprung. The additional 5 mm of stroke length offers 173 mm of real rear-wheel travel. A gain of 8% for unrestrained climbing & descending.

Integration and race-ready routing for a streamlined design.
True to its basic concept, the battery remains external and always easily removable. The GLP III goes one step further in terms of integration,
with the Bosch KIOX display in the top tube and the HMI integrated just above the battery. Cables and hoses are also better integrated, with a routing
in the headset for even cleaner bike lines. This internal passage does not prevent the use of a 150° block lock. However, also developed for UCI competitions, the frame offers «Race Ready Routing», with brake and derailleur hoses routed to the side of the head tube. Last but not least, the frame’s internal guides make the internal passageway silent and rattle free, for an optimal riding experience.

Mullet, not just for the style...
We were determined not to alter the playfulness and liveliness for which the GLP has always been known. Our desire to make the new GLP’s geometry evolve slightly, in line with enduro riding and equipment such as the 170mm fork and the new 205x65mm shock absorber, led us to retain
the front and rear wheel size differentiation. These 2 essential elements have been retained to ensure that the new GLP III remains lively and responsive on technical uphill and downhill sections.
440 mm short chain stay length for technical maneuverability (with a maximum tire section of 2.8). The «Mullet» combo: the GLP III’s differentiated wheel setup reinforces the playfulness of the rear wheel in hairpins, while the front wheel’s rolling characteristics make it easier to negotiate obstacles.

Improving uphill behavior.
To improve uphill performance without losing downhill qualities, we had to make a number of small adjustments to ensure that the rider was perfectly
balanced and at the «heart» of the bike. This translates into:

  1. A straighter seat tube angle of 77° (+1°), in line with the Enduro trend. The rider’s position is now more forward, which helps refocus the centre of mass and reduce the pitch-up effect of short chain stays.
  2. Headset angle changed to 64° (-1°) on all sizes to accommodate 170 mm forks.
  3. Shorter top tube on M/L/XL sizes, but longer reach on all sizes.
  4. A more sloping top tube and a shorter seat tube (-3 cm) to refocus the centre of mass even further.

True to the GLP philosophy, the Bosch Powerpack external battery remains easily removable, and we were determined to keep it that way.
The new PowerPack battery has a capacity of 725 Wh. With 50% more energy (vs GLP2), it’s also 50% heavier (+1.3 kg). The tilt of the battery takes into account its new dimensions, so that the weight is always perfectly distributed in the centre of the bike. That’s why we’ve slightly raised the front of the motor around the bottom bracket axle, so as to lower the rear of the battery as much as possible and reduce the space between battery and motor. These modifications to the position of the motor/battery block therefore rebalance the mass which, combined with the new geometry, makes it easier to tackle technical uphill sections, while giving a sensation of lightness that is unique for a E-MTB.

Motor performance and intelligence.
Engine performance and intelligence perfectly suited to the GLP III’s racing philosophy and spirit, the new limited-series Bosch Performance Line CX
Race drive unit (Team and SE models) generates even more power thanks to its «Race» mode. While it consumes slightly more power than the Turbo mode of the Performance CX engine (Elite model), it has another advantage: it features Extended Boost mode, delivering maximum power over a longer period of time for better obstacle clearance. The CX Race engine also features an intelligent anti-recoil mode and a gear change detection mode to adapt power as you ride. Its low weight (2.75 kg) and 85Nm torque, which delivers up to 600 watts at peak power (400% vs. 340% Performance CX), make the new CX Race the benchmark for competition use.

Bosch app.
Controlling the engine characteristics of your GLP III has never been easier, thanks to the system’s connectivity via the Bosch eBike Flow application
and the KIOX* console. Choosing and setting modes, adjusting power, modulating responsiveness - everything becomes interactive, allowing you to optimize engine performance to suit your riding style. GLP III models feature Race, Turbo, eMTB, Turbo and Off (automatic) modes. *with smartphone connected.
