U350 Product Overview
The same solid, stable and stylish platform as the U500 with some careful modifications to get the price down.
A commercial quality cargo/utility bike for a lower price.
The ODK version 3 is designed from the ground up to be the ultimate car-replacement electric bicycle. Every part has been carefully designed with performance, reliability, practicality and serviceability in mind.
We pored over every detail, listening carefully to the feedback from our customers. We examined how the product was being used and improved any weaknesses. Our 3rd generation ODK platform has really matured and now stands alone in the utility/cargo e-bike category.
The core of the platform: The Battery
New for this season are three interchangeable 48V battery pack capacity options.
A “Standard Range” 15Ah version provides a real world 40 to 50 miles riding and is the most affordable entry to the world of utility/cargo e-bikes.
The 23Ah “Long Range” version pushes the assisted riding distance out to 60 to 75 miles and farther than any other competitor on the market.
The revolutionary “Super Long Range” 32Ah version pushes the limits of e-bike battery technology providing over 100 miles of assisted riding range with 1,536 Watt-Hours. The pack has 4x more capacity than an average e-bike battery and even more than a Toyota Prius!
New motor winding
The robust, sensorless 500-Watt BPM motor has a new winding pattern. Higher average seeds can be achieved while it is now easier to pedal with the motor to extend the battery range. An improved fork with 6 mm dropouts contain the motor’s torque. A new rim and spoke pattern improve the wheel’s durability.
New wiring harness
Small details significantly improve the product. Improved quick-connectors with stainless-steel lock-ring are fitted to all of the connections from the throttle down to the motor connector. Enjoy improved reliability and modern styling.
Full control: We engineer the electronics
The controller is upgraded from 9 to 12 transistors providing powerful and reliable performance. The throttle is re-mapped to give smoother acceleration and delay-free response. New half-twist throttle provides a more linear feel and higher quality tactile experience. The highly popular cruise control function is standard as always.
Absolute Stopping Power
A fast and heavily loaded e-bike needs good brakes. We have chosen the best hydraulic disc brakes available for e-bikes. The stopping performance is absolutely incredible even at max loads or in wet weather. The brake pads can self-adjust as needed, reducing time needed for frequent servicing.
Super Strong Frame
Unlike other bicycle frames, the ODK platform is designed from the ground up to handle the demands of a high-performance cargo e-bike. Even with a wide and low step-thru section, the frame feels very solid due to the custom extruded downtube.
The rack supports have been significantly beefed-up for a more stable loading of child seats and rear rack add-ons. New for the V3 bikes are frame-welded accessory mounts for attaching a front basket or rack directly to the frame. The pannier rail design have been improved to allow for better compatibility with standard bicycle bags. We even added water bottle cage mounts to the down tube.
