You can get your Jasion e-bike road-ready in about 30–45 minutes with basic hand tools (mostly Allen wrenches). The box ships with the battery removed, the front wheel detached, and the handlebars folded or separate. Follow the sequence below to avoid pinched cables, misaligned brakes, or loose hardware.
