Manufacturing with One Hand Tied Behind our Back

Hi all,

Time for us to give you an update on how these lights are progressing.

Delivery Date: It’s mid-January now. That means you can’t give these as holiday gifts – and that makes us really sad. Our advisors remind us, “that’s the nature of startups,” but such reassurances aren’t going to diminish our commitment to getting you the world’s best bike lights as soon as possible.

The Problem: The bike lights have 3 unresolved bugs:

1. Front housing is loose (recently solved! See below for details)

2. Lens on/off button is hard to push

3. Secret battery door is hard to open

The Good News: We know exactly how to solve each “bug.”

The Bad News: We are limited in the changes we can make because we’ve already started the tooling (molds) for the bike lights. We can tweak these molds, but the tweaks must be “steel-safe“. While we’d love to create new tooling, this would push us back 60-90 days - and you can’t wait that long. Subsequently, our engineers are basically designing solutions with one of their hands tied behind their backs.

The Solution: Jonathan, our brilliant new MechE, came up with several workarounds. In short, he came up with a clever way to machine the parts after they come out of the mold, which enables us to test our various solutions to each problem.

Here are a couple pictures we wanted to show you of items we’ve recently machined.

Orange arrows point to the groove that controls the locking of the battery door. These machined “jigs” are designed to dial in the battery collar locking/unlocking tightness. Too loose = water ingress. Too tight and it’s hard to open. We wish we did these 12 months ago but each sample costs ~$1000 and we didn’t have enough money then. Pennywise, pound foolish. Lesson learned.

The front housing of the light was loose. Jonathan, came up with a clever solution: he added “fins” (green arrows) that fit into “holes” (pink arrows) and keep the housing from moving. We’ll explain the jiu-jitsu genius of this over a beer another time, but it is genius.

Next Steps: We’ve been on the phone with the factory from 9-10:30pm four night/week for the last 3 months in order to get these solution implemented. In the coming weeks, our factory will mirror these prototypes in preparation for mass production. Once our solutions have been approved, our Director of Operations (Bruno) will be traveling to Shenzhen to oversee production.

Thanks for sticking it through with us - we can’t tell you how much we appreciate your support.

5 things you definitely didn’t know about bike sharing

Americans Have Taken 23 Million Bike Share Rides and No One Has Died

Let us explain it in numbers

Here’s 5 things didn’t know about bike sharing, by the numbers:

  • 2007 TULSA: the year and the city with the first bike share. Not Portland or SF, but, Tulsa. That’s in Oklahoma (we think).
  • 14% DROP in head injuries in bike share cities. Counter to predictions, head injuries have gone DOWN. Why? More cyclists on the road makes cycling safer
  • 28% DROP in overall injuries for the very same reason
  • 23 MILLION Americans Have Taken Bike Share Rides according to Yahoo.
  • ZERO deaths despite no helmet requirements

Now here’s three ways we’re going to make city cycling even safer:

  1. Helmet-less bike sharing is a time bomb - it’s only a matter of time before the zero deaths number changes. Companies like Helmet Hub are working on this.
  2. Brighter, more rugged safety gear, like our urban bike lights.
  3. Better cyclist-driver relations, as we described on our bicycle blog.

 

What other things will make biking safer?

 

Blame, Frames and Automobiles

Handsup

Ask a city driver to describe the average urban cyclist and they’ll probably describe a tattooed messenger/clueless college kid hybrid. And to the cyclist, cars are unpredictable, door flinging Godzillas hell bent on destruction. There’s plenty of mistrust to go around, but cyclists can seize the opportunity to change the way drivers perceive us and lower the heat on city streets:

  • Ride up, Ride Out Ride in an open way, be assertive rather than aggressive. You have a right to the road, so make your intentions clear, move out of the door zone and into traffic if you have to, remembering that there is a human being behind the wheel of that car, and so:
  • Make Eye Contact If we want to make cycling safer we have to stop looking at drivers as the enemy. This means making eye contact and letting them know that you’re about to turn, stop or cut in behind them. Use gestures, engage them, demystify yourself. At times none of that works so make it your policy to:
  • Let it Slide The world isn’t perfect and cycling on city streets reflects that. You’re going to get cut off, forced out of your lane and cursed at. Resist the urge to settle a score and opt instead for a One Love Marleylike vibe, smile, and keep riding.

Riding with our heads up, making human connections and shrugging off the occasional outrage changes city riding from a series of skirmishes to a guerrilla action of positive engagement; it starts the process of making cyclists and drivers co-owners of our city streets.

 

It has begun

Delivery Update: Shipping begins in August!

The guy all the way on the left is Bruno, our Director of Ops, and don’t let his smile or checkered sweater fool you. Before bike lights he made rocket-science complex, brain surgery precise, die cast aluminum parts for Tier 1 Aviation. And he has just setup a manufacturing line that’d make Henry Ford jealous.

We’ll let the photos do the talking:

Supplier pulling a tooling mold out to cool off. Each one takes about 4 hours to build.

Fresh out of the tool, the first production Afterburner ever built. We’re working toward the “Golden Sample” - the perfect mass production prototype that will be the Gold Standard for the next 50,000 units.

Assembled view. This first part is good but needs to be dialed in for a precision fit.

Custom jig, or fixture, for assembly. Jigs make the assembly process faster and more precise.

Here’s the other thing - Bruno sends a daily email entitled, “Daily Update from the Shop Floor”. You’re seeing what the company sees except we put a X in place of confidential info. This is what you want your Ops to look like.

A. Shop Floor Walk & Production Overviews

I took a walk on the shop floor and saw all of our raw materials that had arrived. About 85% of all parts arrived, with another 5% of parts arriving tomorrow. 9% will arrive Monday 7/28, with 1 part due on Wednesday 7/30.

1. Golden Sample plan

a. Receive raw materials

-Die cast parts - all have passed initial inspection.

-P/N 0302 (Gasket) - This part required new tooling, so these will be finished by Wednesday 7/30.

-Battery Springs - Factory workers are checking the Solderability of these new springs tomorrow to confirm they’re OK for production.

-Micro USB Connector - The bend on the connector is incorrect and cannot be used for mass production. We will use the current ones for the golden sample stage and get new ones for mass production.

-All Other materials: Before Monday

b. SMT

-Scheduled to start Monday July 28, but instead will be on July 30 due to Gasket (0302).

-To get ahead of schedule on other items while we wait for the final parts to come in, we’ll do the following on 7/28-7/29:

-Confirm one more time that the programming works as expected

-Visit vendors (die cast, IM, gasket, screws, etc)

-Adjust fixtures for mass production

-Sign off on all arrived samples by client (me!)

c. Assembly: 7/31 - 8/1-8/2

-This is where we need packaging sample dates from X - pushing DAILY. Contingency plan is Pkg @ X, starting Monday/Tuesday.

-Upon completion we can take up to 3 samples of each model (18pcs total)

d. Product Testing

-8/4 - Optical testing @ supplier

-8/5 - All other testing inside factory

-TBD - Linear testing - waiting on quotes

e. Packing arrival - 8/5 (Critical!)

2. 150pc/model Pilot Run

-8/6 - SMT (based on USB Connector new arrival)

-8/7-8/10: Assembly, Testing, and Packaging

3. Mass Production - Remaining balance on PO

-8/11 - SMT

-8/12-8/26 - FG

-Ship 8/27-8/30 (Partial shipments as needed)

4. Flow 1 Demand (second PO)

-The procurement manager will try to manufacture this at the same time as the first PO, but they need to make sure they can get the materials here in time before committing to that. Answer TBD.

B. Supplier Visits

-Die cast house: 7/28

-Injection Molding: 7/29

-Screw & Tool manufacturer: TBD

C. Cost Initiatives

These weren’t discussed yet, but quotes came in for X this afternoon. Cost is X% lower, with MOQ of 2K/model and lead time is 2 weeks. This is our contingency plan for X.

D. New Product X Discussions

I spoke with Joe about X, but nothing concrete yet. We’ll get more involved on this post-golden sample stage and when I’ve received specs from the team.

 

Want a Word With the Mayor? Then You Have To Race Her!

If your mission is to help your city become healthier and you have a passion for cycling, what do you do? Well, one solution might be to start our own bike race, and this is what Forth Worth, TX Mayor Betsy Price did!

Ms. Price logs more than 100 miles weekly during the summer, and through her passion for biking she has developed the annual event; Tour de Fort Worth. The event was created three years ago as part of the ‘’FitWorth’’ initiative to promote healthy living. Tour de Fort Worth involves more than a dozen rides and gathers over 120 riders. The event is designed to give seasoned cyclists a chance to experience many different parts of the city while sitting in the best seat of all – a bicycle seat. Now she just needs the world’s best bike light.
