We have been working flat out on the new ODK 3's. It is a very ambitious bike and nearly every part has been upgraded in some way. The typical ODK rider puts a lot of miles on the bike. Many of the readily available parts from the bicycle industry are simply not good enough and need to be beefed up or custom manufactured. We intend to achieve EV-Class Performance with our products. It has a much more demanding job than what is required with leisure-class e-bikes. We will try to keep the production status updated as the ODK 3 bikes become reality.
The aluminum frame is the core component to which everything is attached. It is one of the hardest parts to make. Here are some highlights of the new frame design.
Rear Disc Brake Compatibility
The Version 3 platform demanded increased stopping power while retaining internally geared hub compatibility. It is now equipped with Tektro HD-710E hydraulic front and rear disc brakes which gives the bike incredible braking performance. This is the best disc brake avaliable for e-bikes.
The rear disc brake setup required us to upgrade to a SRAM i-3 Hub as the Shimano's 3-speed does not have proper disc brake support. The rear dropout is custom designed to support the rear disc brake. V-brake compatibility is still retained.
Manufacturing this dropout required some extra time and tooling cost. However its worth the effort to avoid a chain tensioner. The new design also puts the chain out of the way of the center kickstand. Additionally, it is one less part to source, stock and support.
Front Accessory Mount
One of the most requested features of version 2 was a front basket. The easy way is to attach a basket to the front fork. This is not a good solution as it negatively effects the steering. The proper way to attach a basket is to weld on some frame-mounted supports. The basket will stay in place while the front wheel is steered from side to side.
The new "Front Accessory Mounts" are spaced 10cm apart and 6cm wide. It uses four 8mm screws to attach anything you can think of to the front of the bike. We will be manufacturing some accessories including a basket which will integrate perfectly with the bike.
Water Bottle Cage Mount
New on version 3 is support for a water bottle cage. We worked to place the cage out of the way, but it is still easy to insert and remove tall bottles. Also there are some interesting accessories that use this same mounting system like the Bike Spike GPS tracker.
Improved Bridge Plates
The ODK has two kickstand bridge plates. Both side and center kickstands can be attached at the same time. The location of the kickstand bridge plates have been better optimized to work with the Ursus Jumbo double leg center stand. It is raised higher and flatter so when the kickstand is retracted, it is less likely to impact the ground during hard cornering.
Improved Rack Design
The rack is slightly shorter than the version 2 bikes but it has been made more functional. The 10 cm x 10 cm rack supports are beefed up significantly. We now have a super solid mounting surface for rack accessories. The rack now slopes more gracefully towards the seat tube.
The seat tube is now lower which allows for a lower minimum seat height of 29.5" or 75cm. Also the seat tube is now using a more common 31.6 mm internal diameter which provides compatibility with mountain bike and suspension seat post such as the Thudbuster. The pannier rails have been offset and narrowed to allow for easier insertion and removal of the pannier bag's hooks.
Improved Riding Geometry
The overall riding position has been adjusted slightly to make the bike easier to ride. The bike feels more "bicycle-like" and familiar to new riders. The end-to-end length is slightly shorter which will give the bike a more compact look and feel.
Pushing the "Copy" Button
The final pre-production frame sample has been signed off and the first production run has started. Bits and pieces will eventually get welded together and later heat-treated. The frames will be cleaned and painted before the various components are installed at final assembly.
