    Generic E-trike Build - KMX+BBS02B and trailer

    Not too different from my trike, I have a 48-tooth ring and a BBSHD mated with the Alfine 8. I shift gently and have had no issues. I am running a 52V battery. I use 203 rotors in front, no rear brake, and stopping is fine. I recently switched to some hydraulic brakes. I am using a piece I got...

    Adapter for Magura Caliper on Stealth Bomber frame

    No idea on the mounting/adapter, but I can speak to the sensor wiring. Two pin levers can be easily adapted to the three-pin with a solder/splice as you mentioned. There is quite a bit of documentation around this - I recently posted having done this with some two-pin Tektro levers. There are...

    Best IGH for BBSHD powered recumbent trike?

    Real-world experience - Two years in to using a Shimano Alfine 8 with BBSHD 52v stock controller, recumbent trike, heavy rider. I shift cautiously, and use a shift sensor. No issues, and prefer it to the previous 9-speed conventional cassette/shifter. Smooth, shifts at stop, and range is...

    Is Tektro Open or Closed switch system for Bafang BBSHD brake sensor?

    For those stumbling on this in future - the answer is the Tektros have two wires, regardless of the way the plug is configured - the two wires are generally blue and black, and are open until the brakes are engaged (normally open switch). For the Bafang three pin connector, you want to connect...

    Brake sensor wiring - again.

    The levers supplies with my bbshd, which I will not be using, actually short the other two pins, 4 and 8, when brakes pulled. The red wire connected to 6 appears unused.

    Is Tektro Open or Closed switch system for Bafang BBSHD brake sensor?

    Did you ever install these with your Bafang, or find the answer to whether these Tektros are normally open or closed? I have a set on order to adapt to BBSHD 3-pin - thanks!

    Brake sensor wiring - again.

    I have seen several threads her and elsewhere regarding adapting 2-pin brake sensors to 3-pin Bafang (BBSHD) connectors. I still am unclear about my specific situation. My question is really to ask owners of Tektro HD-E350 brakes what the actual switch function of the lever sensor is - normally...

    I bricked my BBS02b

    I followed Jon's guide to tweak the BBSHD settings to better mesh the power output of the rider with that of the motor, and can vouch for his assessment that this is not only easy, but transforms these into a real assist motor - from the factory as default, they seem to be set up for somebody...

    Ultimate puncture proof bike tires? testing Kenda K-shield and K-shield Plus

    Those are quite heavy.. I am running a 26" Schwalbe Big Ben Plus at 2.15 wide, it lists as under 1 kg. Tough enough for me so far, no flats.

    RC Drive Recumbent Trike Build

    Looking good. I have an older, hard-tail version of this Performer trike. Be cautious in placing large amount of mass forward of the front wheels. This can lead to steering instability. I would also recommend a hydraulic steering damper if this thing is as fast as it might be.

    Observations from a new to tadpole trike rider.

    I have an unsuspended trike driven by a bbshd mid drive. Climbs well, quiet also. I regularly travel smoother roads at around 20 mph, but find it ok at 30. I have larger tires running at lower pressure. I suppose quick turns would risk roll over at those speeds, but it's a low slung trike and...

    preferred throttle style for indirect steering tadpole ?

    T-Cycle makes an aluminum post that replaces the pivot screw on some bar end shifters like Microsoft and Shimano... This allows a conventional thumb throttle to be mounted right alongside the shifter, in a fairly ergonomic configuration. I will dig up a picture of mine. I actually don't use the...

    A recumbent build

    I have a trike, so am not an expert on battery placement for lwb bents for sure. I once had dreams of an Optima Baron, but I am now too old and fat for that crazy thing! The T-Cycle mount allows for height adjustment and offset, but is expensive. What you have there seems to place the battery in...

    A recumbent build

    T-Cycle has an aluminum battery mount with adapter for any frame tube size.... Pricey, but would let you locate low but out of the way of chain or cracks etc. https://t-cycle.com/products/fully-configureable-battery-mount I have had this for a couple years and it's rock solid

    Why come no tadpole trikes with over seat steering?

    The Wincheetah was built as a speed machine - lightweight, and rather narrow compared to current designs. I think at least one reason for the tiller was that it allows the rider to keep the arms "tucked in" rather than out to the sides, for a more aero approach. To the OP - not sure what is...

    Building the Blue Goose bent trike

    The jockey wheels could work - bigger ones would be better. I think something around 18-20t is what a proper idler would be sized at. They are good as they use bearings. Not sure what the diameter of that stud shaft is, but some combination of spacers and sleeves can get you there. You could...

    Building the Blue Goose bent trike

    With my new trike, the damper solves an oscillation issue, but it's similar to what I used on the old TT. It did improve stability somewhat. Almost any motorcycle damper can be adapted. I actually thought the newer TT solved the issues by design... Mine was a very early one. One area you may...

    Building the Blue Goose bent trike

    Looks like you will have it going soon. I don't knoew much about the Photon - is it basically a 1000 watt unit? It does appear that compared to my BBSHD, the chainline can be made more normal, though on a trike it is less of an ussie. Some pics of my build might give you ideas. I would...

    Building the Blue Goose bent trike

    Sounds kinda similar to my BBSHD trike build - I had used a Harbor Freight Toolbag then an ammo can for a pack battery I used - when it died I went with a basic Hailong downtube battery - expensive, but worthwhile I think, are the battery mounting options sold by Terracycle (T-Cycle) -...

    Building the Blue Goose bent trike

    I have converted my trike, similar to your TT, to e-assist - I started using a hub motor solution, and have since adopted mid-drive. Sounds like your are handy and resourceful - I used a commercially available battery mount from TerraCycle that works well. The wiring and connectors do require a...

    Hub drive from 26" wheel to 20" wheel

    Quick check of circumferences of 559 vs 406 tires shows about a . 75 ratio, so I would estimate the new speed at 19.5, but that is not absolute. You can try the Grin simulator, or even set your display controller etc to the 20" size to estimate. The motor may well be able to pull a higher rpm...

    The SB Cruiser : Amberwolf's 2WD Heavy Cargo Trike & Dog Carrier

    Good tip on the CST tubes - for my trikes' 20" (406) and 26"(559) I started using Schwalbe-branded tubes, maybe some three years back, and have had great success - no punctures (but the tires may be the reason) - a side benefit has been that there seems to be very little air loss over time...

    Sully's BBSHD Programming

    I also tried your approach for my trike - works well! I modified PAS levels 4-7 to match what you did, but kept the upper and lower ranges for an "economy" setting along with a full power range, I did tweak the "Pedal Assist" screen also. The mid ranges definitely allow for a more natural...

    Greenspeed Magnum Big Wheel with 'stoke monkey' motor and Gates Belt drive

    Very cool setup - the picture obscures the chain routing from boom front through any idlers and to the motor mounted cassette - that's a unique part of this setup. Can you do regen braking? I am assuming the right side chain is freewheeled and the belt drives the motor continuously? I am...
