    Helmet Safety Protection Ratings

    The rating is relative to the other helmets submitted for testing. Your helmet is still 5 STAR rated, it‘s just that there are now 102 other helmets rated better…..obviously helmets have improved since the previous test relative to yours.

    Seth prefers Schrader valves

    Maxxis do a 27.5 x 2.00/3.00 tube which will obviously fit a 2.8 tyre which is OEM for the rear mullet setup on my Frey Beast. It’s not a threaded schrader (like the AV19 schwalbes on my other bike) but the stem is 48mm which is ample length to grip with your fingers when locking on the schrader...

    Ebike-Specific Chain Versus Regular Chain for Mid-Drive Ebike (Pictures!)

    Just saw this timely post over on the EMTB forums with a member sharing their comparison of chains, SRAM XX1 chain compared to a couple of Shimano chains. No measurable wear on the XX1 chain. Sounds like the XO1 and XX1 chains are the ones to buy. As mentioned above, I’ve also been surprised by...

    Ebike-Specific Chain Versus Regular Chain for Mid-Drive Ebike (Pictures!)

    I have been looking at the X01 chains as a possible replacement, however I have seen posts where the hollow pins have been crushed on more powerful M620 builds.

    Re-greasing the Ultra motor...is it time?

    Several e-bike shops in Australia recommend the Mobil 28 grease. It has an NLGI of 1.5 per the data sheet, wide temp range with very low starting and running torque (low drag).

    Ebike-Specific Chain Versus Regular Chain for Mid-Drive Ebike (Pictures!)

    My strategy is based on what I hear when I shift and I have adapted the way I ride accordingly. To this end, upshifting into a taller gear, particularly on the Bafang powered bike, is met with a clunk if I dont back off the pedals prior to the shift. There is no such clunk when downshifting into...

    Bafang Ultra Motor (M620) Longevity - How Long Should They Last?

    Arguably one of the most reliable e-bike motors out there. Built like a tank with all steel gears, no nylon gears or belts here. Downside is weight and noise from the all steel gears (depending how generous the worker was with the grease on the day). Uart versions are programmable. I have 60v...

    Ebike-Specific Chain Versus Regular Chain for Mid-Drive Ebike (Pictures!)

    KMC e9 chain on Ananda powered hardtail ebike with shift cut - I only got circa 800klms before it was unrideable (badly slipping on gears). LBS put a 10 speed chain on it (not sure of brand) for free and it’s done circa 1,000 klm without issue. Shifts are also crisper with the 10sp chain. Sram...
