Mongoose XR-Pro Build

Post by captaingeek » Dec 02, 2017 12:19 pm

Hi All,

Wanted to gets some helpful feedback on my XR-Pro build. Suggesting a different frame or bike is not helpful so please do not reply if its off topic.

I'd like to purchase everything from a single vendor. I'm open to building my own battery etc.

I"m willing to spend up to $1,500 on the motor, battery and accessory's.



I'm thinking of a bafang mid drive kit from Luna Cycles:
https://lunacycle.com/mid-drive-kits/
I like the look of the BBSHD or maybe the Ultra.

BBSHD, good. Bike, not good. Start with a better bike, even if you have to get a used one to meet your budget.

Your topic is a request for feedback. Chalo is definitely not wrong. Walgooses are not particularly good bikes. It more than likely has a plastic bushing for the main suspension pivots. A BBSHD is gonna torque the rear end. Components (brakes, derailleur, etc.) will all be low end. Also, you mentioned the Bafang Ultra. Those require a specific frame to work.

You asked for feedback and I gave it to you straight, the same as I would for one of my own customers. You may resent my advice because you already made your critical mistake-- but it's probably the best advice you'll get from anyone on your project. Correspondingly, ignoring it would be the most effective way to prevent the long term success of your build.

You reported someone for giving you honest and accurate advice!? Ive had a bunch of people here point out my mistakes, Ive learned from them and ended up with a faster, safer, more efficient bike. Drop your gaurd a little bit mate, no one is here to prevent you from acheiving your goals, but we have a communal obligation to each other to point out when someone is doing something unsafe. Youd be best pairing it with a BBS02 and upgrade key components. Brakes would be my first port of call. Keep us updated on how the build progresses!

His FEEWINGS was hoitated. (Damn left wingers fighting among themselves again.)

$1,500 worth of parts on a $99 bike. Chalo, whatever possessed you to think he wanted something GOOD?

Having built on something similar to the bike here, in my case it was the Mongoose XR15 that someone gave me, the bike proved worth every cent I spent to acquire it. The 450w Currie kit may have been a bit overpriced at close to $300, but the performance of the Mongoose made me wish I'd paid even less.

I still have the Currie kit I could put on something else if I wanted. That Mongoose. . . ?

Meanwhile, if you have a Fry's electronics near you, check out the $699 bike that's much like what you're trying to build. Seriously. Maybe you could build on the XR Pro with this more suitable investment: https://www.yescomusa.com/products/brus ... -motor-kit

I am going to to do basically the same build. I picked up a Mongoose XR Pro for $123 that was brand new. Do you think Luna's Shark Pack would fit inside the frame? I printed out their drawing to size, cut it out, and held it in place and looks like it would fit but, just barely.

How do you like your setup?
What is top speed?
How does it climb?
Did you have any install problems?

TIA,

Manx

Battery won’t fit in frame and be removable. Could probably be semi permanently mounted in there which I considered. Even if you remove the spring in order to remove the batt you still won’t have enough room. Range isn’t that great but probably about 25 miles with pedal assist.

Already have a couple of hundred miles on it and still a lot of fun. Max speed without pedaling is about 25mph. Easy to do 30 with pedaling. No problem climbing.

Removing the stock crank set is a bish. I pretty much stripped out one side. Make sure u have a good removal tool the one that can’t with the Luna tool set is sheet.
