eBike peg prototype is finished

8/22/2015

1 Comment

 
The prototype modified peg for ebikes is finished and ready to test out and verify it works. There are two modifications to tour standard bike seat peg with this prototype.

The first is a slot cut out of the side of the peg, to allow the power/throttle wire to feed through and back into the wheel. The second is the hole for the peg was tapped to M12x1.25 (12mm diameter by 1.25 mm thread pitch). This peg can screw directly onto 12mm diameter axles and does not require axle nuts to tighten down onto the frame.

To install this peg, you'll disconnect the power/throttle wire from the axle, unscrew the existing axle nut, then screw on the ebike peg, feed the wire back through the slot in the peg, and connect it back up to the wheel.

I'll provide more pictures of the peg once I've been able to install it on an appropriate ebike and make sure it works. Once it's proven out, I'll make these pegs available on the website!

Prototype Pannier hooks arrive in SF for inspection

8/19/2015

The first prototype pannier hooks arrived this week from the factory for review and they're very close to being ready for manufacturing. There are a couple of details to work out with the specs, and we're requesting a second prototype from the factory to iron them out. But based on the turn-around with the first prototype, we should be able to start manufacturing within the next month!

Foot Peg Solution for eBikes

8/11/2015

1 Comment

 
eBikes today come in all sorts of different configurations: rear-wheel drive, front-wheel drive, mid-drive (power is applied to the crank set where the pedals are). For some rear-drive systems, the motor is housed in the center of the rear-wheel, and the throttle and control wire feeds in to the motor through the center-point of the rear-axle on one side. To date this configuration has posed a serious challenge to installing a Companion Bike Seat because this wire gets in the way of properly installing the peg onto that side of the rear axle.

Last week I started working on a potential solution for this eBike setup, and I'm making good progress! Below is a picture of the almost-finished "prototype" peg, with a slot in the side to be able to feed the throttle wire through after installing the peg onto the axle. The only thing left is to get the proper sized tap to thread the holes of the peg so that it screws directly onto the axle (without required axle nuts). Once this is done, I'll be able to do a test-install with this updated peg and see if it works!

Depending on how the test installation goes, I will hopefully be able to offer these "eBike pegs" for purchase on the website very soon!

Photos of the first prototypes of the pannier hooks for Companion Bike Seat arrived today from the factory! The edges are a little rough and the paint job needs some cleaning up before it's ready for manufacturing, but overall they look good ... definitely headed in the right direction.

A little cleaning up of the rough edges with a file, then the prototype pannier hooks will be shipped here for physical review and testing.
