Hello Endless Sphere!
Long time lurker, first time poster. I would like to start off by saying thank you to all those who make this place such a wealth of information and support. I can honestly say that my bike and business would not be where it is today if it wasn't for endless sphere. I'm also lucky enough to live in the same town as the wizards of Grin Tech aka ebikes.ca so a special thanks to Justin and Robbie and all the grin tech crew. Thanks to Paul at EM3EV as well for great customer support.
I have a long john style cargo bike that I built last summer that I use for my appliance repair service. I built the frame from an old Nishiki and steel square tube in my garage using a miller mig 120v welder and basic metal work tools like a grinder, drill press, and chop saw. Everything fore of the handle bars is home brewed (and slightly crooked :lol: ) including the fork. Custom heavy duty drop outs in the rear with disc mounts. The storage box I had welded by a local shop as it's aluminum and I have yet to get the gear to weld it. I had rough plans on paper but nothing concrete so I knew the mark 1 would be a learning experience. I essentially copied the old dutch bakfiet design. I hope to build another, much improved bike in the future because boy, I REALLY learned a lot (made many mistakes). I'm happy to report that despite the bumps and challenges along the way, the hacking and grinding and redoing, the bike really is a pleasure to ride, easy to control at low and high speeds and even rolls in a steady and straight line! Bike specs are as follows:
50kg curb weight 150kg gross weight with rider, tools, and part stock.
22AH 16s EM3EV pack
Mac 8T
40A 4110 Infineon controller
Cycle Analyst 2.3
Satiator
BB7 disc brakes (shimano hydro rear on the way)
Schwalbe Marathon 20" front 26" rear
60km range with 750 watt limit, fully loaded in urban conditions with pedaling. 80km range possible with light payload and lower wattage settings.
In the past 9 months or so, I have put on over 4000kms on my set up, hauling on daily basis, 25kg of tools and parts. My record payload was 240kg (530lb) incl rider but not including bike. I've had an amazing time transforming my business model to a sustainable and satisfying one. A few build pics can be seen at http://downtownappliance.ca/blog.html. Recent upgrades have been a 12v system for charging electronics and running LED's plus a new amazing cycle Satiator! I keep my pack and charger inside a vinyl leather projector bag as I have to remove the battery from the bike to charge. I installed a fan in the bag with a 40C bimetal to switch the fan on and off and 10k thermistor to control fan speed. The bag also has a spare 120 outlet plus USB power for the fan and accessory charging in the front pouch.
Here's where I'm at now. The "winter" conditions and extreme work load have put a lot of stress on my mac motor. I have been thoroughly amazed with the low speed torque and over all performance, but I want to make the switch to a direct drive motor for reliability and serviceability. I'm looking at the Crystalyte H3540 as a suitable replacement, mainly due to the improved cable routing and intrinsic simplicity of the design plus of course performance. Weight isn't really an issue as the bike is already a damn cow. I'm keen to hear feedback and recommendations on motor options plus anyone who might have experience with the H3540 motor. Here are a few photos of the bike throughout the past while.
Early build phase pre-box. In fact, That's the aluminum for the box right there in the cargo area!
In it's urban habitat!
Here's some of that extra paylod I was mentioning.
Large pizza compatible. This is before I got the larger pack, satiator and pouch. I can show a more recent photo of the inside fitted for a work day with tools, parts etc if folks are interested.
Front 5mm LED's with red and green for port and starboard. I may add an LED controller for different light modes.
Rear LED's
Pack and Satiator living happily ever after inside an enclosed space thanks to the 5v fan system. Early photo, please forgive the protective plastic. I left it on until the bag was complete. :lol:
Discreet? I hope so. Security/bomb threat? Maybe. Harper would probably think so.
Bag rear showing fan exhaust.
A happy rider, dishwasher, and bike enjoying the so called winter weather.
Thanks!
