Begode: T4 PRO QC Report

Frequently Asked Questions

What are the benefits of the T4 PRO vs the V3? The T4 PRO is an iterative upgrade, according to Begode, the main capability is that it provides 25% more torque at lower speeds than the V3. Other major hardware changes are the use of the latest 130mm 1,300lb shock (normally sold for $350 extra), the latest Samsung 50S high-powered battery pack to have both the high-performance without any range sacrifice that one used to have to make in choosing between the 40Ts & 50Es.

What would be reasons for considering the V3 over the PRO? V3s are in stock, ready to ship. It’s considerably less expensive, not everyone needs/wants the capabilities of the PRO. The V3 also has the choice of tires, the J802/knobby, or CST-1773/hybrid tire.

Do the handle-kits come standard with the T4 Pro/Pro+ No, but these can be purchased separately

What charger is packaged in the box? A 100.8V/5A that supports auto-switching 110/220V input sources.

What is the maximum rate of charge?
Both our V3 & PROs contain the higher-power cells, that are rated for a large input current. While at a cell-level, the packs are rated up to charge up 20A, there’s other limitations of the charge-board, wiring & BMS, 15A max is recommended, e.g. a rapid-charger & stock 5A concurrently.

I’m concerned about the shock’s maximum supporting weight. Has this been addressed? The current air shock has rebound & is reputed to support Riders of up to 135kg/300lb limit. The latest 1,300lb coil/spring shock can support loads of up to 330lb. Additionally, the PRO has a separate 900lb coil in the box, for lighter Riders, or those who prefer a plushier ride that the lighter spring offers.

If I wish to fit a different tire, are all 16×3″ tires compatible with the T4/PRO? Yes, all these motors have a standardized rim of 3.0/12″ & there’s plenty of clearance between the frame assembly & tire.

How water-resistant is the T4?
While Begode does not conduct IP x testing on their Wheel, based on statistical data over the past year, the probability of water percolating down into the sensitive controller area is low. Nevertheless, no Wheel should be kept outdoors, exposed to the elements & try abstain from riding in a heavy downpour. Bearings are susceptible to corrosion/wear from riding in a saline environment, despite the bearing seals.

Will a high-torque/high-speed motor option be offered?Begode has developed the T4 motor unit in-house that combines both high-torque & a ‘no-load’ rotational speed of 78KPH/48.5MPH—Please note that the actual max ride speed should be at least 15KPH below the max cut-out speed; or ~58KPH/36MPH.

Begode T4 Electric Unicycle

Begode’s T4 is the first 16″ suspension Wheel, packed with a battery pack/motor combo that would normally found in a large 18″ machine like the S18, V11, & Hero. While the initial introduction has seen its share of troubles related to the same motor slipping condition found on the earlier S22s, Begode has since changed their motor supplier from ZX to QS, resulting in improved reliability. In addition, the controller has been redesigned incorporating an addition 6 MOSFETS, from 12x to 18x, for improved contoller load-sharing.

Package size & weight: dimensionally the T4 is 26H x 10.6W x 17.7L, making it one of the most compact suspension Wheels produced today, & 10lb lighter than the comparable Hero. For those who commute, in buildings with flights of stairs, these incremental pounds can make all the difference in practicality of ownership.
Battery Improvements: in addition to the upgraded high-powered Samsung 40T battery packs [for our production], Begode has added some much needed BMS safety improvements that include temperature probes on the BMS, line-protocol communication with the controller, & short-circuit protection.

Durable Construction: compact, yet rugged metal frame construction, using improved stainless screws/bolts. The motor has a beefed up 50mm wide rim for better stability/tire fitting & greater resiliance against deformation & damage.
100mm of Suspension Travel: despite the smaller size,there is up 100mm of vertical travel, 20mm more than the Master, EX20, & MasterPro. This T4 uses the latest 4d generation Begode shock, with adjustable rebound settings, maximum chamber pressure of 300psi, supporting loads of up to 285lb.
Choice of Tires: depending on your needs, Begode is offering the choice of a knobby/off-road tire J802, or a CST-1488 street tire—the original CST-1773 hybrid tire will be available later.
Standard equipment: there are some decent value-adds that are included as standard here: like the mud-guard, set of Powerpads, die-cast spiked pedals [shipped separately for initial production] integrated seat & the charger has been upgraded from a 100V/3A to a 5A for faster <3hr charging.

The principles of battery selection on PEVs are complex but can be distilled down to a general rule of ‘the smaller the battery pack, the more power is demanded from the cells’. The T4 battery pack comprises 24 cells in series & 4 parallels (24s4p), the same configuration as the RS, Nikola+, etc. Since the surges in peak power output are more significant than on the earlier generation hardware—more powerful controller & motor—it’s essential that the battery pack matches the capabilities of the rest of the machine, minimizing cell stresses & brown-out potential.

While the new BMS architecture possesses improved safety mechanisms—temperature probes & short-protection—the hard lessons of history have demonstrated that latent fire risks may only be manifested years later. For this comparatively small machine, we deem it essential to require this model to be equipped with a high-powered cell, the Samsung 40T. Beyond the safety/performance benefits, other advantages include faster-charging potential (up to 8-10A), superior pack longevity, cooler operation, increased performance, and more efficient energy utilization from the battery pack.
