Building an etrike

[cloughjs]

Building an eTrike for my girlfriend so she can get around town. She likes to take her little dog with her and she’s only 150cm tall so we decided on a 26” folding trike. Thinking a mid drive but I also want to use a front hub motor so it has part time awd. How would one go about tying the front hub motor and the mid drive to the same hand controls?

Be patient, save yourself some work.. I'm getting one from Lectric for my in-laws, they are close to 145 cm tall.

Lectric XP Trike

$1499 for an e-trike, I might have to get one just for kicks. Folding frame makes it even more enticing. https://electrek.co/2023/01/09/lectric-xp-trike-electric-tricycle-teaser-revealed/

RadPower eTrike

$2499.. is a bit more than I'd like to spend on a e-trike. I like the short wheelbase, looks to make it really nimble and able to make tight turns. https://electrek.co/2023/01/11/radtrike-review-testing-rad-power-bikes-electric-trike/

Unfortunately both of those are out of my price range …. And I like having a project. I just finished the 2000 S10 I bought for my son… it’s too cold to go outside and lift my Jeep….. waiting on parts for my motorcycle…. So that leaves her trike

To start with I would recommend balancing the power a bit probably use an inexpensive 250 watt front hub drive,with a TD2Z 350-500 36 VOLT MIDDRIVE,be reasonable and save some money , now you do not want this thing to be super fast because of stability concerns, actually you shouldnt need a dual controller just get a battery splitter, with both motors going this thing will eat hills, the Tongsheng middrive has built torque sensor( simplify) the hub motor can use throttle and or PAS. The TDZ middrives are reasonable price with up to 80 nm torque and you can dig around and find a used 26" 250 front wheel for under $50 and use a 'brick battery to save money, yada,yada, the sensors will give a good amount of control and so on.
I am planning on building a 750 -36 volt reverse trike for stability, keep us posted please, if you have the donor trike already it should be easy to make this thing under a $1000.
For anyone interested "Signal" a Chinese company makes the conversion kits for a leaning reverse trike for around $300.
