Yes, you can.

Yes you can, you will need lights with the Fazua style power cord and a dealer can help get them installed.

The Fazua Ride 60 battery on the Heckler SL is desgined to be charged while inside the frame, and only removed for service.

Fazua firmware updates can be installed either via the Fazua phone app, through consumer Fazua Toolbox desktop software, or at your local Santa Cruz Bicycles dealer.

Absolutely. Learn more at Fazua's Garmin support page linked below, which includes the latest list of Garmin compatible devices, what data will display on your head unit, and how to connect each.

No, your bike is pre-programmed and ready to ride straight from the factory.

The FAZUA App connects to your bike via Bluetooth, and allows you to view live riding data (I.E. power output, & battery percentate of charge). You're also able to select different assist modes, download new riding profiles, and update your Fazua system's firmware.

Fazua Ride 60 uses cranks with the ETOR spindle interface.

In North America, the Heckler SL will have a pedal assisted max speed of 20mph/32kph.
For Europe, and majority of the world, the pedal assisted max speed is 25kph.

There is no throttle. The Heckler SL is pedal assist only.

Mixed wheels provide the stability and traction of a 29" front wheel with the agility of a 27.5" rear wheel. The smaller rear wheel and its comparatively lower axle height allows the rider to more easily unweight the front wheel- this makes for confident yet agile handling on the steepest of descents. Additionally, on e-bikes specifically, the motorized drive unit does a good job propelling the rear wheel through rough terrain, without hanging up or losing momentum.

The largest compatible rotor diameter is 223mm, and the smallest size is 200mm.

The Heckler SL geometry is optimized for a 44mm fork offset.

29" bikes provide a ton of front wheel grip- this is partially due to the front wheel itself, but also due to the axle height of the rear wheel which works to keep the front end weighted. This creates a natural position on lower-angle terrain but requires body position and/or setup adjustments to achieve any sort of rearward bias.

On an MX bike, the bias is more rearward. This gives a very natural feeling on steep descents, but requires some body position and setup consideration for a balanced feel on flatter terrain. Compared to a 29er, a slightly lower handlebar and a more forward-biased suspension setup will make an MX bike feel more like what you're used to. Additionally, using the Hi BB setting will lend itself to a more front biased feel. Using these tuning parameters will help you find the sweet spot for your terrain and preference.

You'll know you have it dialed when it feels like you're never making large bodyweight shifts to either lift the front end or keep it stuck to the ground.

An MX bike will definitely handle differently than a full 27.5 bike. The main difference you'll feel is a more stable and confident front end. The turning will be a bit slower than a 27.5, but the payoff is a more secure feeling in corners and more traction. Due to the taller front axle height and improved roll-over of the large wheel, your chances of stuffing the front wheel or going over the bars is vastly diminished. Use this security to ride challenging terrain with a more aggressive and dynamic body position.

The chainstay length change occurs in the front triangles- we vary the pivot locations fore and aft to achieve the different lengths while using a single size swingarm. So no- you cannot get the chainstay length of the small on your size large, for instance.

Yes.

These bikes are designed specifically to use mixed wheels. We do not recommend a 27.5 front wheel for geometry reasons.
