    Mongoose Dolomite QC

    I spoke with Amber from Mongoose about the newest version of the Dolomite, the black frame and blue rim version from Walmart for $189. I received one from Walmart.com and tore my bike down and inspected the wheel bearings,handle bar bearings and finally the Bottom Bracket bearings and all made no noise and we're properly adjusted. The bearings had ample grease on them. The previous version that was metallic blue with red rims seemed to have inherent issues with too tight of bearing torque and lack of grease. The newest bike version also has good mechanical 160mm disc brakes. When I spoke to Amber from Dolomite about the older Dolomite bikes vs the newest type she said that Mongoose has increased their QC or Quality Control. Next step is to install a 1000 watt BBSHD with a kit from Luna Cycle now that I know the bike runs well as a regular peddle bike and is a good candidate to make an ebike out of it like many other bike enthusias do. I'll let you know how the 120mm BB BBSHD works out with a LT48 volt 14 Ah battery from Lyndsey works out.Thank you Amber from Mongoose.Tim from flat and windy Kansas

    If you can get a usable bike for less than a set of bud and lou's, more power to ya.

      It was meant as a compliment not a critique.
      Perhaps I need to put smileys on my posts to prevent bunched panty syndrome

      A lot of times I am not a good communicator. I just toss it out there and expect others to harvest the goodness of my ramblings.

    I know bike shops like to say BSO (Bike Shaped Objects) are meant to be sold NOT ridden and I can understand why they feel that way. But for under $200 the frame probably isn’t going to fail anytime soon and if workmanship has improved that makes it an even better bargain.

    Personally, I desire a little better quality components and of course 8spd cassette so I find the Gravity Monster to be more my thing. But it’s $500 and if you’re not sure if this eBike thing is for you, Dolomite is not much money to gamble.

    Keep us posted on the progress and setup!

      I purchased a Walgoose Hitch for my first build. It had most of the QC problems mentioned above: very little grease on bearings, headstock and hubs so tight they were difficult to turn, smaller bolts also so tight I thought I would break something getting them loose. Luckily all ended up being easy to fix. I replaced all the components I thought needed an immediate upgrade while waiting to electrify the bike. I changed out the seat, headstock, pedals, shifter, and brake levers. While not necessary, I will also swap the 7 speed (14-28T) freewheel for wider range (11-34T) and put a 203mm rotor on the front. Total investment = $281. I've been looking at the Monster. If my build does what I hope for, a Gravity will probably be where the BBSHD ends up. I figure I have little to lose while I learn on a $200 bike.

    Some time ago I asked Ebike1 who is over on "High Voltage High Speed Hub Bikes" what would be a good ridged stiff frame to build a performance bike on. He told me a Mongoose Hitch.

    Short thread, last three posts are relevant. http://electricbike.com/forum/forum/...me-390-shipped

      I'm in the process of adding the Luna Lander forks. I may also add a Thudbuster. I figure all this can get moved to a different bike, if I see the need. I wanted to stay with a steel frame and figure the extra 10 pounds of a Hitch over bikes that cost $100's-$1,000's more isn't the end of the world when you've got e-power along for the ride.

      Years ago when just about the only thing available were Crystalyte motors their instructions were to buy a heavy Walmart bike for the beginnings of your project. Under no circumstances were you to use Aluminum.

      Holy shit you got that for 189 bucks, we get price gouged here in Aus, you'd be lucky to get the fracking tyres for that here...

    I even painted the large and small hose clamps gloss black to match my frame. The controller way painted with radiator gloss black paint as radiator paint is special as it helps draw heat away. I removed the decal on the controller and replaced it after painting to keep the stock 40 amp look. I also used the water bottle mount for the controller. Thank you,Tim.

        It took all of 3 hours from start to finish to have the 3,000 watt Cyclone Motor spinning away. It is an easy kit to install with my 30 some years in as a Bodyman in a Body shop. It was very enjoyable to do. All the wiring was plug and play.

          Hard to beat the new Dolomite or the Hitch for a easy and cheap e-bike build. I hope the new dolomite has better hubs and rear axle than the old one.

            New Mariner, what was the problem with the hubs and rear axle? The reason I ask, is that I had used a Sears Porter Iron Horse frame for my fat bike build. Today, after 600 miles, the rear hub bearing assembly disintergrated. Rear hub needs to be replaced, but cant find a 190, 36H hub anywhere. So now looking at moving all the motor and such over to a Mongoose Dolomite. Thoughts? Kerry

            i am not sure what the exact problem is? I have not had any issues so far. But others have. Join Mongoose fat bikes and ask the question there. I got a 170mm freehub wheelset waiting in the wings. Will cold set my rear end to 170mm. Advantage of steel. That is only 20mm each side.
