I forgot to mention that before I bought anything I told them what my optimal riding goals were with an ebike, and they recommended the setup I have. It's a lower power setup, I wanted to get as much exercise and range as possible without over-stressing my knees, so I would use low to medium...

You have it exactly. It's a little hard to remove the iZip wiring from the down tube but once you do you can run your own wiring through it, to keep it out of the weather and protect it from impacts, and it looks clean. The controller has two heavy wires, red and black, that connect to the...

I removed all of the old hardware and replaced it with Grin stuff, (order details below.) Grin has excellent customer service, I emailed them many times even apologizing if I was being annoying, they were totally supportive and answered all of my many questions... I recommend you consider asking...

Definitely agree. If you don't find an easy hack, LPL (linked above) sells a tool that makes it easy, you can find similar tools cheaper if you shop around.

The Grin Baserunner controller allowed me to set the max speeds (Throttle & PAS separately) and the Power Assist max power and increment size in Watts, Using 100W increments and leaving it at the lowest setting - so far it clocked 24.6 miles and still has 51.7V in the 48V battery! It's perfect...

During the lockdown I watched a lot more youtube, this channel teaches you how to pick locks, I got a cheap lockpick set from China and have picked over a dozen locks, you might be surprised how easy it can be once you've seen how they're built. If you can pick it you can get it rekeyed for not...

I know this is an old thread but I'm wondering if you ever figured out what was wrong with your bike? Was it the bottom bracket, or cassette?

What did you end up doing with the bike? I got a 2015 E3 Dash with a fried motor, put a Grin Shengyi geared SX2 motor, PAS, display, brake handles, controller, throttle in it for $671 total including tax and shipping. The motor performs great and the controller is highly configurable, e.g. how...

I'd like to thank AHicks for writing about his experience with geared motors for hill climbing, and RunForTheHills for talking about his experience with Grin and their customer service. I emailed them several times and they handled all of my technimcal questions perfectly, I went with their...

I'd like to thank everyone who posted here, this was really educational for me. I liked what AHicks wrote about geared motors, and that RunForTheHills liked Grin for their customer support. I emailed them a few times and watched several of their YT videos & decided to get their Shengyi DGWX2...

Did you buy a motor yet? I'd like to hear your opinion if you did. If not you may find this interesting. Small Geared Hub Motor Showdown, Bafang G311/G310 vs Shengyi SX1/SX2

Good to know, thanks.

That's been my experience, thanks. I look forward to the day when we have a superstore that carries all of the major brands and parts and you can see what you're buying, with an easy in-store return policy.

I found this kit on AliBaba, it's a great price, includes wheel, KT display & controller... the ad is a little wonky, doesn't show motor dimensions, says 20A KT sinusoidal controller but pictures show 10A ?! Does anyone have experience with this seller, or an opinion about this kit. My neighbor...

Thanks, I'm the same way lol, and the LCD-3 looks good to me too. If we can figure out how the signal from the temp sensor is connected to the meter, and changed in any way, we could conceivably build a circuit to do that if the controller or a direct connect doesn't work. I don't even know how...

The improvement in mileage is significant. I didn't expect to see that. The KT-LCD3 can *display the engine power draw (W), or temperature (C or F), I emailed a few people asking if a compatible controller is needed or if the motor temp sensor has to be connected directly to the display...

Thanks harryS, good to know, If I go that route I'll look for KT controller+display that show motor temp. What model LCD do you have and do you like it?

Thanks AHicks, I appreciate hearing your thoughts and experience. If Grin tech costs too much I'm leaning towards the suggestions here - Bafang motor w/my 10 spd cassette and KT controller & display. I have to research regen braking and if geared motors / KT controllers offer that, and if there...

Thanks, I've been emailing Grin bikes, they have a controller that reduces power when temperature reaches a certain point, so you don't fry motors, like mine. The Bafang & KT setup looks good too. I'll get a price back from Grin soon then decide what setup to use. I can move the wheel to the new...

I was going to follow AHicks suggestions: "Perfect would be a 500w Bafang with waterproof KT controller (KT 22-A), and KT display of choice. I specify waterproof KT for their absolute simplicity when it comes to wiring the bike up." Having a clutch sounds good. From what I read it sounds like I...
