Ease of conversion?
The alloy is very soft for a grinder. Here's what I had to do on my Norco Storm 2 to get the Tongsheng motor to fit:
Is the hollow area for internal cabling? Is that part of the frame supported on just the sides or is their internal framing? Thanks!
To me it doesn't look structural, just cable routing. It is welded on to the underside of the down tube. However, I am not an expert, I could be wrong. I am only using this bike for road and dirt tracks, not downhill or jumps, so I wasn't too worried about it.
I am in the process of installing a new shift cable along the outside also. I can swing the motor up; just not as far because of the internal cable housing. I would be reluctant to take a grinder to my TREK.
No haven't started yet. But based on my conversion to Tongsheng motor on a similar MTB for myself I will route the cables on the outside with cable ties and will probably have to get the grinder out on the external cable routing alloy to fit the motor in. Sounds like a big job but it's only 5 mins with the grinder.
Did you finish your build? How did you configure the internal cables?
My wife's Trek Dual Sport 3 MY2020 has nasty internal cable management that runs over the bottom of the bottom bracket. Presumably these wires need to be pulled out and replaced with covered cables?
Hi, I'm looking into buying an E-bike for my wife and discovered this site and the option of converting her existing bike. I bought her a Trek Dual Sports 3 Women's bike in 2020 see here. Seems like the perfect conversion candidate, however her bike is a small which has a lower top bar. Do you think I could still convert it? See below for sizing chart and dimensions.
How did it go? What did you end up buying and from where. I'm going to do a similar bike, Specialized Sirrus X, size medium.
That's a perfect bike to convert, 1 x drive train. I would get a BBs02 Bafang 750v, legal in federal and most state trails. I would also get the Lekkie 40t Sprocket kit, would be the same size as stock if you are getting a 2022, so you won't even have to bother with changing the chain, or fooling with stock gear ratios, just bolt it on. If you like bling I like the Lekkie cranks, they look much nicer than stock, especially the silver. I love the eggrider display, programs from your phone, a little more expensive but a lot less hastle. This will out preform the $5,000 - $7,000 e-bikes Trek sells.
bike looks easy! large triangle frame plenty of space for a good shark or triangle battery. like advice for most builders, consider your main use case. conversion is generally straightforward. see other conversion videos for what u might want or search my post to see my completed build with my list of accessories. good luck
